I like it!
Note: I must say, I wasn't planning to buy Brink, then D2D was offering 25% off its pre-orders, and a few friends were getting it, so peer pressure won. I must say that I have been looking for a decent multiplayer game with decent BOT support (because bots don't call you hacker and ban you off their servers

) as well as all the good customization stuff that CoD has, and Brink provides that. Even the single-player campaign was enjoyable, gameplay-wise, there wasn't any effort put in the storytelling at all, all I could gather was, the resistance were living the hobo-dream, but somehow along the way, they got a lot of high-tech guns and equipment, then decided to escape the ark, while the Security folks want their little hobo to behave. Oh, and there was this guy who kept reminding about how the Security folks are mean, every single cutscene. Finally, the AI, a lot of reviewers say that they are DUMB, but I didn't feel that at all while playing the game on normal, they worked on accomplishing their missions the best they could, and they completed 80% of the objectives for me while I was trying to jump over a table, so I like brink, hopefully modding tools will be released for PC.
And yes, it's Team Fortress meet Call of Duty with some of twists from Quake Wars: enemy territory were each class can have their own little mini-objectives that they can do if they are not able to help with the primary ... like ... locate some land mines. Yep.
