If you're a fan of the Warhammer 40k universe, or if you just love ridiculously over-the-top action, you might want to give Warhmmer 40k: Space Marine a try as it's entirely free to grab for the next ~25 hours. Simply head on over to the Humble Bundle website, sign up for the newsletter, and you'll be able to blast Orks and Chaos fanatics at any time you want.
As for whether Space Marine is actually worth the trouble, I would say the answer is a bit of a cautious yes. It's not the most complex or lengthy game around, and the last time I played the multiplayer scene was fairly dead, but all of that pales in comparison to the sheer amount of carnage you can wreak with a chainsword and a jetpack! So if you're up for an action game where you can turn off your brain and enjoy the spectacle, Space Marine is likely to be right up your alley.
Since trying to explain Space Marine through words alone is a bit of a pointless venture, allow me to send you off with one of the original trailers. It's a fairly short one, but it should give you a pretty darn good idea of what sort of nonsense you can expect. Enjoy!
