Amazing fast action.
What I loved the most about this game is that it not only throws an insane amount of action at you, but it rewards you for being able to make quick decisions while under fire. Should you go for the guy closing in on you, or attack a group of guys that are far away to get more points, are you in a situation where you need to use a bomb or should you save it for the tougher levels.
I like that, as you go through the game the levels get darker and the music gets more intense. The first few levels have simple bright backdrops but later levels have dark out of this world backrounds with intense pounding music.
While similar to the first Overrun the little improvements make this vastly superior, new and better enemies, great upgrade system, scoreboard. There are still a few improvements that could make the game better such as adding different hit zones for enemies, where shooting a stickman in the head would give you a one hit kill, but little things like that don't effect my opinion of this game at all.
