Some more details about Dead Island's upcoming "Bloodbath" downloadable content have surfaced, revealing that the package will contain four survival maps, which do exactly what you think they do -- pit you against an endless horde of zombies.
The zombies really will be endless, too. The aim of this survival mode isn't to actually survive, it's just to see how far you get before you die. You'll earn points along the way, and there will be a jolly good time had by all.
I'm a sucker for any kind of wave-based survival mode, so its inclusion is perfectly fine by me. Bloodbath will be released later this month, and there's a code for it if you pre-ordered the thing. No word on how much it'll cost the "normal" folk.
