Did you see today's hot new Unreal Engine 4 graphics demo? And read about how it will change the games we play on the next Xbox and PlayStation, perhaps?

Well.

We have even more UE4 demo videos to share with you. These are some crude game prototypes that Epic principal artist Shane Caudle cooked up using the Unreal Engine 4's game-scripting tool Kismet. He made them, an Epic rep tells me, in a matter of hours or days.

These are obviously just programming tests, not $60 real games, of course. But if you want a first look at something game-like running in the engine, here you go. Plus, there's shooting! Games are better when they have shooting, right?

(Also: Keep an eye on the lighting in some of these.)
