nice try
i think if you buy this game for the xbox live function your gonna be pretty well off but of your buying it for the single player you will be sorely disappointed. the single player is so short its crazy and you could beat it in a day. i would reccoment this game to multiplayer but for singleplayer junkies. stay away. but if you like a gun game that has alien killing action plus some gore here and there i guess you will be ok. but i was dissappointed in microsofts efforts in this game. but dont let me influence your decision
