The Army has been using video game technology in combat simulations for years. And as technology has gotten better, those simulated battlegrounds have appropriately started to leap off the screen.
Just look at what they're doing with the CryEngine 3 . Here are two trailers from the new Dismounted Soldier Training System; bear in mind that you're looking at a $57 million project from RealTime Immersive, Inc.
The first trailer is called an "in-game cinematic" and it's rendering a very large area.
The second shows off the technology involved, and that includes combat and what appears to be a little convertible submarine.
No, sorry, this is specifically for training purposes, so you won't be able to "play" it. But at the rate we're going, Call of Duty will look like this in a few years time. …okay, maybe not CoD with its 73-year-old engine that Activision refuses to upgrade, but some shooter might look like this.
