The best FPS I have ever played.
Pros:
You aren't getting ripped off
Let me repeat, you aren't getting ripped off! Updates with new maps and content come all the time FOR FREE!
The graphics are awesome for a Source game. (Can't wait till Source 2 is out.)
The gameplay is balanced
It's tacticool as ♥♥♥♥
The playerbase is on the rise
The Coop isn't too easy and it's not too hard
It's rewarding for really smart and good play
I could go on forever but those are the most notable ups

Cons:
There's a learning curve. The maps are complicated and they take awhile to get used too.
It is really buggy. I play on a Mac so I can't vouch for PC, (My PC exploded before I got this game.) but there are lots of problems. Most of the time it's weird things at launch like the screen going white for two seconds, or the game glitching for a half second. Nothing too interruptive, though rarely there are game crashing bugs.

The developers are trying to grow the player base and make it more friendly to new players, and they are still bug testing and fixing. It's not perfect, but with a little time it will be one of the best FPS games ever.

P.S.
Get it now so you can get pro before it gets big.
