The Overwatch beta was a blast and the game looks simply gorgeous.
I decided to grab a bunch of screenshots and a few ripped models and have a look at how Blizzard are making Overwatch look the way it does.
A lot of this is just speculation, I very well could have gotten something wrong in here.
To clarify, I did not work on Overwatch, that would be amazing though xD
I also compiled the slides into a PDF for those that want to download: (EDIT: Updated link, contains some corrections)https://drive.google.com/file/d/0Byjlw-rmzZZwQTFvQkpobVpqUUk/view?usp=sharing
Also posted it on my Tumblr if that's your jam:http://agiledev.tumblr.com/
]Note: These slides are a little out of date, check the PDF slides for a slightly updated version with some of the corrections you guys have suggested.
