I'll be honest. When I first heard of the game I thought it was gonna be just another below average shooter. Warhammer 40k: Fire Warrior came to mind. It was thankfully much better than I expected.:) I find the Warhammer 40k universe to be enjoyable in games, but not my favorite (I'm a huge Star Wars fan) so the gameplay was the main thing for me. If only there was a new Star Wars 3rd person shooter. I'm looking at you non-existent Battlefront 3.

Many of the previews seem to be fairly similar of course.

It even has a video for it. It looks awesome. This isn't directly Space Marine related, but it's still awesome.:)
