Installed this and played a few hours late last night on 360. Did the escort / parkour challenges up to 2 stars, unlocked a bunch of stuff, and enjoyed setting up my trash-bag wearing light bodied medic. Jumped online and had about a 50% success rate finding non-slideshow games, which is basically unacceptable but hopefully it's just launch madness and they'll get it sorted out this week. At least they don't penalize you too heavily for quitting out and let you keep a bunch of your earned xp.
I'm feeling forgiving towards the game since when I get into a solid match it's been really fun. The parkour is definitely skill based and really opens up how you can move around the battlefield. Once you start looking for them, there's all kinds of shortcuts and the slide-tackle really makes it possible for a single fast player to fuck up an unsuspecting group of enemies. The shooting feels good, I'm still experimenting with weapons & attachments trying to find the right fit. Graphically I love the art style. The texture load-in is definitely there and the IQ certainly isn't great, but once I was running and gunning, buffing and reviving it wasn't noticeable. The lighting and atmosphere is gorgeous.
Story wise the opening faux papercraft intro is amazing, but you really lose any sense of narrative once you get playing. Having cut-scenes to open the levels is okay, reminds me of Killzone 3s operations mode, but they really should have A) included your player model, and B) ditched the conflicted character dialogue. Make it about the here and now, get me pumped about how it's us versus them! As it is, I'm completely divorced from any narrative.
Brink really is a weird beast. It reminds me most of my experience with MAG (R.I.P. PSN) which I grew to love despite its oddities because ultimately it offered something completely unique, which is pretty rare in console multiplayer. If you're someone looking for an involving good single player campaign, there's nothing for you here. Get Crysis 2. Personally I feel like this game's got great potential for teamwork class-based fun, and it'll be my main MP fix till BF3.

Yeah, definitely do the challenges first. I went back at the end of the night to do the objective challenges and to attempt escort 3, and got totally owned. I was level 7 by that point, and suddenly there were heavy bots laying down tons of fire with sentry guns and mines all over the place.
