Best boss by far has to be The End. You can't beat the initial feeling of paranoia when you enter a new area as you don't know where he's hiding or if he can see you. I really like the way its just a proper one-on-one sniper fight to the death, it's so much more satisfying than the other Cobras who just use a predictable pattern of attacks. And most of all it's such a class feeling sneaking up on him and taking his camo. I'm not sure why I just really enjoyed doing that-maybe because it took me so long and real
tactics are needed.
I always could count on Futures
