I'm not sure how to feel about Bulletstorm's ending. I mean, there was nothing wrong with it, I liked the twist they threw in a lot, but after that, it was just so abrupt. Granted, to actually finish the story would've made the game twice as long, and I get that they're going for "replay value", but that sort of thing does nothing for me. I'll probably get a few hours of fun out of Echoes, but nothing more. I might play some more Anarchy, too, but I'm really hoping they'll add something more with DLC, be it multiplayer modes, guns, skillshots, whatever.
Still, it's not so bad that I won't say this: best FPS since CoD4, easily. Possibly even better, depending on what you're going by. It's a brilliant shooter with a lot of good, well-executed ideas ( skillshots, slow motion, a lot of neat tricks ... enemies are barely a threat, more like props for you to execute in the most elaborate ways possible ). It has a pulpish story that, all the same, is great, and delivered even better. The humor is a mix between dumb, pointless profanity and stupidity, and impeccable timing. It's not just mildly amusing one-liners.
Man, what more can I say? I was expecting a bit of entertainment to keep me going until DA2's release, but this game completely blew me away.
