HOTD: Overkill... How about HOTD: Shortest game ever!
The gameplay is classic arcade rail shooter.The levels are broke into 7 or 8 GrindHouse like "movies". ( Sort of like Left 4 Dead,but not anywhere near as cool ) At the end of each short level there is a lame boss character, all of which are very easy to beat. You earn money for completing various challenges during each level that you can use to buy and upgrade different guns from the Gun Shop. This part of the game is cool,im not going lie. But its kinda pointless. By the time you make enough money to buy the really good guns, you've already beat the game. And if you do go back through with upgraged guns there is NO challenge what so ever. After you beat the regular game you unlock the "Director's Cut" which is just the same thing but with fewer continues and a bit tougher enemies. If you make it that far without being bored to sleep you unlock dual-wield mode after beating the Director's cut.
Overall,Overkill is not that bad. Its kind of like a drunk midget hooker...short, easy, and not worth 50 bucks. Its worth a rent... just dont buy.
