Dont believe the bad reviews, this game is good.
This game is fun plain and simple. You have a melee weapon, a primary weapon and a secondary weapon. your objective is to kill anything and everything that moves. With over seventy different types off monsters, thats lots off killing to do. you also collect parts and tokens to buy and upgrade you weapons.
The weapons in this game are cool. you have your standard nail-gun, nad launcher, shot gun. but later in the game you will get some really cool stuff, like the radioactive flashlight, cellphone tazer, and much, much more. very cool. Im not going to lie to you, the game does have some issues. The checkpoint system sucks, plain and simple. after collecting all of your tokens and parts through out the level, if you die without hitting a checkpoint, you loose it all. Even with some of these issues, the game is still really fun. Plus the dev's promise that a patch will fix most of these.
If your into old school games, I would highly recommend you give it a try. I took a chance, and im really glad I did.
