lol, of course you got that much. I mean look how many zombies there are, and you are last human with the bonus damage. Try getting that on a normal round with 30 players. first when i got last human they were 12 zombies and the time left is 8 min, but most of them got bored and left My brother got over 1000 SP in one kill I dont know how i know how it hapened with me but as a zombie not human, i got 950 sp buy proping a human in the air and from behind, got 4 combos of skill points
