Avoid if you haven't bought. Although if you consider the cheap price, maybe...
Anyway my copy arrived from Play today too, wasn't expecting much really and that's what I got.
Fiddled with the CD key for ten minutes.
This is the first game I've come across that didn't let me install it where I wanted.
The DX10 graphics are 'passable'. God it's soo consoley.
The controls suck: no next/prev weapons, controls changing on the fly etc. There's a joypad option! - which sad ***** play these games with a joypad? Jeez.
Admittedly I've only played as a marine for 15 mins (in the club area, under seige from a few aliens...one at a time actually), I'll probably give the game another go later, but you don't need to get that much further into a ****ty game to realise it's just that.
