A very awesome game. You get a giant bionic arm and a set of guns as you travel though a city. Killing people and boss all the way as you swing from wall to wall. Hacking Relays and learning new ability's. So if you like action and adventure. Play Bionic Commando for the Xbox360! But most achievements are 5,10, 15,30, or 40 Gamerscore. To get most of the achievements, you have to complete challenges. For one achievement you must find all collectibles in the game,and the other for are for betting the game on different difficulties. Over all it's one of the best games I've ever played!!!!!!
