Behead The Undead is the name of
Challenge Mode level 1-A in
TimeSplitters, a
first person shooter for the
Playstation 2. As the rather amusing name hints at, your job is to behead
zombies...50 heads in 2 minutes, to be exact. Completing this specific challenge unlocks a number of zombies as
playable characters in
multiplayer.
Also, in a nod to the original, this is the name of a subset of levels in TimeSplitters 2's Challenge Mode, which also focuses around removing heads off of various zombies, in one way or another.
