Aliens Vs Predator

Anyone played this yet? I want to buy it this weekend, looks awesome.

for me its one of those games which could be either a complete surprising success or a complete failure,
im looking forward to the alien mode online whereas one alien starts... then who ever he/she kills becomes an alien... and so, all whilst the human remaining players try and survive, last human wins : p

From what I've heard it's an excellent game for any of the Fans and apparantly the campaign is really long which is good to see for once.

I'm mainly looking forward to playing as the Predator, always wanted to just be alone, hunting and killing enemies Muahahahaa!
