900 megabytes. uses ue3. vibration off in default setting. it's a ww2 game and there's three classes. commando (tommy gun + revolver), ranger (sniper rifle + colt), or covert op (silenced machine gun + knife) and covert op can cut barbed wire fences. At the beginning of every checkpoint you can choose which class to use. you're basically indestructible, one time when I got stuck in a stairway I threw two grenades in front of me and I didn't die, might have gone through the floor though. you have to turn the sensitivity way up. The graphics are pretty good. the grenades are the wimpiest I've ever seen. make sure you sprint or you could die. you can't shoot when you sprint but you can reload. health recharges slow. the vehicle controls are shit. you have to point from the vehicle's perspective and the machine guns aren't attached to the turret so there's really no point in firing them. the physics are super messed up and you can scale up a wall by driving towards it and flip your tank over and blow it up. I did that on accident. had to finish demo with a rocket launcher that was very satisfying.
