I don't know, I haven't tried.

What I can say that it won't make a game last for an infinite time. Because to put 1 HP into a dead hog, you have to sacrifice 1 HP from the current hog.

Why don't you just triy it? You can go into the game, and create a weapon scheme to just try that out. Try it out online and see how players respond.

Hedgewars is largely customizable, after all.
