Its like the DSII engine a bit, The demo lacks but I will get it.
From what I see and hear its not party orginized though a sidekick/F'n-Pet shows up later (God I hate pets).
Heres the lamens, Its Halo on DSII engine, Alien Shooter style with syndacate body mods (Come on, Tell me that doesnt hit the nail on the head)
Only downfalls so far are,,,, Key remap not so good, Its like Halo inventory not DSII, and the worst downfall is you dont get to design your own looks, I know my little girl wont play it long since she doesnt like to be "Dude as she says and alot of guys like to play the ever hot combat vixen.
