Got my copy yesterday, single player was boring so I switched to multiplayer. Played till 5 am in the morning , and then woke up at 11 am to get ready for work
Btw guys, if you want decent low ping servers to play - In the Server browser, search for "Fragnetics" . I get around 70-100 ms ping to them, they're based in Singapore.
Edit : Had a graphical glitch with my GTX 560Ti , there was no ground , almost as if you were walking on a mirror. Updating to the latest drivers fixed it.
And of course, I got pwned relentlessly early on. Camping in this game really spoils the fun. But I love how you get points for providing suppression fire and lots of other tiny extras.
