I find it way harder in Versus mode now that there's Charger, Spitter, and the ever so annoying Jockey.
Seriously either i suck (most likely) or people have gotten better being infected, they have such coordinated plans. Like a Boomer would be hinding in a corner then puke on us, then the horde comes, we usually clump together when one of us gets puked on, but then the Spitter comes out, and hurls out her acid puke, we are nearly dead and usually a Jockey would come and drag one of us further out to their doom.... But nope a Charger comes out and kills 1 survivor. The horde finally dying out we forgot about the Boomer who booms us again..... *tear*
Though it's aweeesome. And since I'm kinda young playing this game, I'm not so freaked out because that some of the game chapters are during the day.
