Actually, I don't. I didn't play Warhead (yet), but I really liked only the 1st part of Crysis. I've had enough of fighting aliens. So a continuation of Crysis/Warhead surely will have lots of aliens. But a prequel is a different story.
Yes I purchased Warhead and finished it , I liked it , has got some good reviews...It was a bit more action packed , I thought the sound effects were well done too....
I don't know which ending I liked better, the one in Crysis with the huge alien mothership or the one in Warhead with hundreds of those aliens.
I was actually talking about the battle, not the ending itself. The endings weren't that great but I liked the battle.
