I got this XBLA game free as well. I recieved it for buying my Xbox360 at a certain time. I got this game along with Joust. This is bascially a port of the original Robotron : 2084 game. I don’t think there is anyhting different about it. I have only been able to make it to maybe the 5th or 6th wave. This game sort of plays like Geometry Wars, but seems alot harder for some reason and the game is old. It is a pretty hard game. Maybe back then, they use to make arcade games really hard to play so you would keep dropping quarters into the machine.

I don’t really recommend this game unless you either can get it for free, or you love retro games. More information on Robotron : 2084 can be found here.
