Anti-Hero

This battle is very similar to a Hero battle. This battle pits a few hard-to-kill people against the entire rest of the field. The entire rest of the field is led by its own hero (the anti-hero).

Regen: None, though Heroes and anti-heros are very hard to kill (see below)
Teams: Heroes versus anti-hero + team. The Heroes side should be horribly outnumbered, perhaps 7-10:1. The ratio of heroes to anti-hero + team and the number of hits a hero and anti-hero can take can be adjusted as appropriate.
Rules: Heroes do not count their own armor, and their sheilds cannot be broken. Heroes do not die as normal and they never lose limbs - instead they keep a running count (out loud) of how many hits they've received regardless of type or location (a single green to the leg counts the same as a red to the chest). Once they've reached a predetermined number (10-20, normally), they die.
Normal people die, lose limbs, count armor, and have their sheilds broken normally.
Tactics: Heroes must keep running, constantly, and must win through attrition. Heroes normally die by becoming trapped, surrounded, falling, etc.
The anti-hero has an advantage over the heros because he can choose to fight or have the rest of his team fight for him. The anti-hero mostly is a way to counter the formidable hero team.
