In this 2017 GDC session, Brightskull Entertainment Group founder Michael Csurics showcases the experimental and extensive lengths that were taken to create the voiceover performances in Fullbright’s space station exploration game Tacoma.

It was an intriguing look at how the game’s experimental voice-over recording process was created and implemented; Csurics walked the audience through how, with indie resources, the Tacoma team was able to capture 6-on-mic ensemble scenes while giving the actor’s freedom to use full body movement, theatrically performing every scene with crystal-clear audio fidelity.

Whether you work in big-budget game dev or a tiny indie team, this is a talk with useful takeaways you can apply to your next project — so take advantage of the fact you can now watch it for free over on the official GDC YouTube channel!

In addition to this presentation, the GDC Vault and its accompanying YouTube channel offers numerous other free videos, audio recordings, and slides from many of the recent Game Developers Conference events, and the service offers even more members-only content for GDC Vault subscribers.

Those who purchased All Access passes to recent events like GDC or XRDC already have full access to GDC Vault, and interested parties can apply for the individual subscription via a GDC Vault subscription page. Group subscriptions are also available: game-related schools and development studios who sign up for GDC Vault Studio Subscriptions can receive access for their entire office or company by contacting staff via the GDC Vault group subscription page. Finally, current subscribers with access issues can contact GDC Vault technical support.

Have you ever heard of a hero that always needs to be saved? No? Well, then get ready for the first one. Hero (yeah that’s how he likes to be called) is the only guy standing between the planet’s safety and 11 monsters that are trying to bring havoc everywhere. Why does he always need to be saved? Simple. He’s as forgetful as they come. He’s about to fight an ice monster? For sure, he forgets the fuel for his flamethrower! How about fighting a flame-breathing dragon? Obviously, he leaves his fireproof shield at home! It’s in these situations that he calls for backup, and here’s where the Hero Express comes into play. They’re the best of the best when it comes to deliveries. Their motto? “Heroic deliveries, right on time!” Delivery Guy (yeah, stop asking! It’s his name!) is the one they always send in these dire times. He’s their best man when it comes to delivering packages fast in dangerous places and never fails to do his job splendidly! Do you have the skills to get Delivery Guy to the end of each track in this 2D physics driven driving game? Cause Hero Express is already available on Xbox One!

To get to the end of each track you need some skills, as you don’t want your vehicle to topple over and break the package you’re delivering (at least we hope you don’t!). But you can also upgrade your car with the coins collected on the track and make its 4 stats (engine, wheels, traction, and stability) more powerful. But in the end the skill is what gets you to the end of the track, so here’s a couple of tricks for you.

By using the left analog stick you can tilt the car midair to balance it, doing air tricks and landing safely. This is a pretty basic skill that any player learns pretty early in the game, but there’s an advanced trick to it. What you might not notice is that this trick works even when the car is touching the ground, thus being able to balance it or to do wheelies. As the car starts with traction only on the back wheels this can be used to climb high hills. Try tilting the analog back as to do a wheelie. This will minimize the impact between the front wheels and the hill, while also keeping the rear wheel steady on the ground. With this trick you can climb hills way higher than you normally could at your level!

A second trick is related to the Jumper item. It’s an item that can be collected to make high jumps and reach otherwise unreachable areas. Normally it’s used to get to alternative routes on the track, to get other items or to avoid pits that would result in a game over. The trick is to just keep a few of them (most times one is enough but you never know) until you reach a hill you can’t pass yet. When you start climbing it immediately use the jumper. This will hurl you upwards making you reach a higher point at a speed you wouldn’t normally have thus giving you higher chances to reach the hill’s top.

These 2 tricks aren’t really necessary to finish the tracks of course, but will help you beating them in no time. What to do after that then? Each track has a hard mode. A modified version of the track that’s way more difficult to beat. Sometimes it’s even longer and includes parts that weren’t there in normal mode. These hard versions will really put your skills to test and the tricks we talked about will be invaluable when challenging them.

If you like how Hero Express sounds then you should get ready for this crazy driving adventure.

Hero Express is available now for Xbox One the Microsoft Store. Click here for purchase details.

Cuphead may well be one of the most well-received 2D run ‘n gun platformers of recent times, but how would its standout aesthetic have looked if everything was in 3D instead? If you’ve been hoping to find the answer to that very specific question, you’re in luck.

Raf Grassetti, art director on God of War, has recreated the game’s heroes Cuphead and Mugman. We’ve actually featured his work on the site several times over the past few months; he’s been sharing different takes on beloved gaming characters, including a large portion of the Super Smash Bros. roster.

That’s not all for Cuphead and co., though, as Grassetti has also recently posted these designs for King Dice and the Devil. We think they look great, even with Cuphead’s original art style being so important to the game’s overall feel.

What do you think? Are you a fan of these designs? Remember, Cuphead is soon getting its very own Netflix show.

Earlier today we disabled a loophole that allowed players to purchase two of the Weekend Bundle rather than just one. Enough people exploited this loophole that we have decided that, for the next 24 hours only, we will give a chance for players who did not exploit it to also buy up to two bundles total within the client directly.

Newly announced Twitch distribution deal drives an average audience per minute of 408,000 for the opening day broadcast

IRVINE, Calif.–(BUSINESS WIRE)– The Overwatch League roared to life last week at the Blizzard Arena Los Angeles, with four days of intense competition between all 12 teams of the world’s first major global city-based professional esports league.

Buoyed by a newly announced two-year deal with Twitch, the Overwatch League’s exclusive worldwide^[1] third-party digital broadcast partner, opening day drew an impressive average audience per minute of 408,000, and 280,000 for the week. More than 10 million viewers tuned in over the four-day period via Twitch, MLG, and Chinese streaming partners ZhanQi TV, NetEase CC, and Panda TV—not to mention the countless additional viewers at watch parties worldwide. On Twitch and MLG alone, the peak concurrent online audience of 437,000 hit during the highly anticipated day-one matchup between Dallas Fuel and Seoul Dynasty. In addition, tickets to Blizzard Arena Los Angeles were sold out for the entirety of opening week.

“We’re thrilled by the overwhelming response to the Overwatch League’s opening week of play,” said Pete Vlastelica, president and CEO of Major League Gaming (MLG). “But this is only the beginning. With more than 35 million Overwatch® players, the Overwatch League has the potential to become one of the most-watched leagues—of any kind—in the world.”

“Since we announced Overwatch League at BlizzCon 2016, we’ve been eagerly awaiting the day when the global competitive Overwatch community could come together under one banner,” said Nate Nanzer, Overwatch League commissioner. “Opening week was that coming-out party—for the fans, both in-person at Blizzard Arena Los Angeles and tuned in by the millions all over the world, and for the players, whose love for the game came through crystal clear.”

“We had high expectations for the inaugural broadcast of the Overwatch League on Twitch, given our platform’s passionate fanbase for Overwatch,” said Kevin Lin, COO of Twitch. “They really put on an amazing show and fans showed up en masse to support and celebrate Overwatch. Based on the response from the community, Overwatch League is off to a great start and we look forward to watching how the season progresses. This league demonstrates the power and potential of esports, and we’re thrilled to continue expanding our partnership with Blizzard.”

Viewers can tune in to catch all the action on Twitch, www.mlg.com, the MLG app (on iOS and Android), www.overwatchleague.com, and the Overwatch League app, which launched last week for iOS and Android. Blizzard gamers also can get easy access to the Overwatch League via a new Overwatch League tab in the Blizzard Battle.net desktop app.

The first season of the Overwatch League runs until June, with playoffs and finals scheduled for July. For the inaugural season, all regular-season games will take place at Blizzard Arena Los Angeles, a state-of-the-art live-event venue in Burbank, California, custom-renovated for Blizzard Entertainment esports events. Fans can purchase tickets to attend matches, which will be played each Wednesday, Thursday, Friday, and Saturday. A full schedule and information about ticket sales can be found at www.overwatchleague.com.

This week at Bungie, we watched Guardians hunt for Truth.

Season of Opulence is off and running. Guardians are piling into the Emperor’s lost vaults in search of the treasure of their choosing. Earlier this week, you discovered a new boss waiting for you in the depths of the Menagerie. Upon defeating it, you were given a quest to seek out Truth. Not in an X-files way, but to find the Rocket Launcher, Truth—a weapon that seeks out its targets… aggressively. Just look at what some players are seeing in the wild:

Next week, we’ll mix things up once again with a third additional boss to keep things fresh in our new six-player activity. And that’s not all we have planned. We are also welcoming an old friend back to the Tower.

Iron Pursuits

Lord Saladin will return next week for the first Iron Banner of Season of Opulence. With a new Season, you have a fresh set of weapons and armor available to earn. Saladin continues to offer Iron Banner bounties, but will also set you on a quest to earn your gear. In other words, prove your worth, and be outfitted as an Iron Lord.

Here is a preview of the armor and weapons available during Iron Banner events in Season of Opulence.

Valor boosts will also be available next week in Iron Banner and the rest of the Crucible. Saladin will also have some other items available including this new Emblem.

Raid Stats

Thousands of Guardians explored deep within the Leviathan to tackle the challenges of the Crown of Sorrow raid. A fireteam of six completed it first and paved the way for others to follow in their footsteps. We made a graphic showing the number of Guardians who beat the raid in a few key timeframes during the first week.

Congratulations to everyone who has completed it so far. If you’re still Powering up, Gahlran is waiting for you.

In the past, kings and leaders used oracles and magicians to help them predict the future — or at least get some good advice due to their supposed power to perceive hidden information. Nowadays, we live in a society obsessed with quantifying everything. So we have data scientists to do this job.

Data scientists use statistical models, numerical techniques and advanced algorithms that didn’t come from statistical disciplines, along with the data that exist on databases, to find, to infer, to predict data that doesn’t exist yet. Sometimes this data is about the future. That is why we do a lot of predictive analytics and prescriptive analytics.

Here are some questions to which data scientists help find answers:

1. Who are the students with high propensity to abandon the class? For each one, what are the reasons for leaving?
2. Which house has a price above or below the fair price? What is the fair price for a certain house?
3. What are the hidden groups that my clients classify themselves?
4. Which future problems this premature child will develop?
5. How many calls will I get in my call center tomorrow 11:43 AM?
6. My bank should or should not lend money to this customer?

Note how the answer to all these question is not sitting in any database waiting to be queried. These are all data that still doesn’t exist and has to be calculated. That is part of the job we data scientists do.

Throughout this article you’ll learn how to prepare a Fedora system as a Data Scientist’s development environment and also a production system. Most of the basic software is RPM-packaged, but the most advanced parts can only be installed, nowadays, with Python’s pip tool.

Jupyter — the IDE

Most modern data scientists use Python. And an important part of their work is EDA (exploratory data analysis). EDA is a manual and interactive process that retrieves data, explores its features, searches for correlations, and uses plotted graphics to visualize and understand how data is shaped and prototypes predictive models.

Jupyter is a web application perfect for this task. Jupyter works with Notebooks, documents that mix rich text including beautifully rendered math formulas (thanks to mathjax), blocks of code and code output, including graphics.

Notebook files have extension .ipynb, which means Interactive Python Notebook.

Setting up and running Jupyter

First, install essential packages for Jupyter (using sudo):

$ sudo dnf install python3-notebook mathjax sscg

You might want to install additional and optional Python modules commonly used by data scientists:

$ sudo dnf install python3-seaborn python3-lxml python3-basemap python3-scikit-image python3-scikit-learn python3-sympy python3-dask+dataframe python3-nltk

Set a password to log into Notebook web interface and avoid those long tokens. Run the following command anywhere on your terminal:

$ mkdir -p $HOME/.jupyter
$ jupyter notebook password

Now, type a password for yourself. This will create the file $HOME/.jupyter/jupyter_notebook_config.json with your encrypted password.

Next, prepare for SSLby generating a self-signed HTTPS certificate for Jupyter’s web server:

$ cd $HOME/.jupyter; sscg

Finish configuring Jupyter by editing your $HOME/.jupyter/jupyter_notebook_config.json file. Make it look like this:

{
 "NotebookApp": {
 "password": "sha1:abf58...87b",
 "ip": "*",
 "allow_origin": "*",
 "allow_remote_access": true,
 "open_browser": false,
 "websocket_compression_options": {},
 "certfile": "/home/aviram/.jupyter/service.pem",
 "keyfile": "/home/aviram/.jupyter/service-key.pem",
 "notebook_dir": "/home/aviram/Notebooks"
 }
} 

The parts in red must be changed to match your folders. Parts in blue were already there after you created your password. Parts in green are the crypto-related files generated by sscg.

Create a folder for your notebook files, as configured in the notebook_dir setting above:

$ mkdir $HOME/Notebooks

Now you are all set. Just run Jupyter Notebook from anywhere on your system by typing:

$ jupyter notebook

Or add this line to your $HOME/.bashrc file to create a shortcut command called jn:

alias jn='jupyter notebook'

After running the command jn, access https://your-fedora-host.com:8888 from any browser on the network to see the Jupyter user interface. You’ll need to use the password you set up earlier. Start typing some Python code and markup text. This is how it looks:

In addition to the IPython environment, you’ll also get a web-based Unix terminal provided by terminado. Some people might find this useful, while others find this insecure. You can disable this feature in the config file.

JupyterLab — the next generation of Jupyter

JupyterLab is the next generation of Jupyter, with a better interface and more control over your workspace. It’s currently not RPM-packaged for Fedora at the time of writing, but you can use pip to get it installed easily:

$ pip3 install jupyterlab --user
$ jupyter serverextension enable --py jupyterlab

Then run your regular jupiter notebook command or jn alias. JupyterLab will be accessible from http://your-linux-host.com:8888/lab.

Tools used by data scientists

In this section you can get to know some of these tools, and how to install them. Unless noted otherwise, the module is already packaged for Fedora and was installed as prerequisites for previous components.

Numpy

Numpy is an advanced and C-optimized math library designed to work with large in-memory datasets. It provides advanced multidimensional matrix support and operations, including math functions as log(), exp(), trigonometry etc.

Pandas

In this author’s opinion, Python is THE platform for data science mostly because of Pandas. Built on top of numpy, Pandas makes easy the work of preparing and displaying data. You can think of it as a no-UI spreadsheet, but ready to work with much larger datasets. Pandas helps with data retrieval from a SQL database, CSV or other types of files, columns and rows manipulation, data filtering and, to some extent, data visualization with matplotlib.

Matplotlib

Matplotlib is a library to plot 2D and 3D data. It has great support for notations in graphics, labels and overlays

Seaborn

Built on top of matplotlib, Seaborn’s graphics are optimized for a more statistical comprehension of data. It automatically displays regression lines or Gauss curve approximations of plotted data.

StatsModels

StatsModels provides algorithms for statistical and econometrics data analysis such as linear and logistic regressions. Statsmodel is also home for the classical family of time series algorithms known as ARIMA.

Scikit-learn

The central piece of the machine-learning ecosystem, scikit provides predictor algorithms for regression (Elasticnet, Gradient Boosting, Random Forest etc) and classification and clustering (K-means, DBSCAN etc). It features a very well designed API. Scikit also has classes for advanced data manipulation, dataset split into train and test parts, dimensionality reduction and data pipeline preparation.

XGBoost

XGBoost is the most advanced regressor and classifier used nowadays. It’s not part of scikit-learn, but it adheres to scikit’s API. XGBoost is not packaged for Fedora and should be installed with pip. XGBoost can be accelerated with your nVidia GPU, but not through its pip package. You can get this if you compile it yourself against CUDA. Get it with:

$ pip3 install xgboost --user

Imbalanced Learn

imbalanced-learn provides ways for under-sampling and over-sampling data. It is useful in fraud detection scenarios where known fraud data is very small when compared to non-fraud data. In these cases data augmentation is needed for the known fraud data, to make it more relevant to train predictors. Install it with pip:

$ pip3 install imblearn --user

NLTK

The Natural Language toolkit, or NLTK, helps you work with human language data for the purpose of building chatbots (just to cite an example).

SHAP

Machine learning algorithms are very good on predicting, but aren’t good at explaining why they made a prediction. SHAP solves that, by analyzing trained models.

Install it with pip:

$ pip3 install shap --user

Keras

Keras is a library for deep learning and neural networks. Install it with pip:

$ sudo dnf instal python3-h5py
$ pip3 install keras --user

TensorFlow

TensorFlow is a popular neural networks builder. Install it with pip:

$ pip3 install tensorflow --user
