Necromunda: what happens to plague zombies when they go down?
Downed zombies act the same as any other downed ganger: their movement is a 2" crawl (the plague zombie's owner chooses the direction), and they make the same end-of-round injury check as any normal ganger. The only exception is that if a plague zombie rolls a "1", it doesn't take the flesh wound as it stands up. This makes plague zombies about as tough as any other ganger: with the exception of close combat, it takes an injury roll of "6" to take them out.

If a downed zombie "charges" into combat, it simply gets taken out automatically, just like any other ganger that crawls into combat (unless there are multiple combatants, of course).

As a side note: in the fluff, plague zombies are still alive &ndash; just brain-damaged by the plague. So it makes sense that all of the rules of living gangers apply to plague zombies, with the exception of the rules that apply to pain or psychology.
