Still unsure if you want to partake in the curve stomping of Orks or ripping the flesh of Chaos Marines, or think your too cool for a game that originally had to played with a pen and paper. THQ hears you, and want to give you a taste of their Hammer by releasing a Demo of Warhammer 40K Space Marine.
The demo is set to release on XBLA and PC August 23, with a PS3 version arriving August 24. It will feature two levels — one in which the player faces off against a horde of invading greenskins, and another that showcases the Jump Pack.
And if you really like it, pre-order at Gamestop Canada/EBGames to earn a chance to win a Chainsword!
