It's kind of like the temple as in that there will be a lot of death and only one person can win. Basically the group must hold out as a team as long as they can against the zombies. The alpha, or original zombie won't die, but can be slown down, delayed, etc. Every person he kills become's an infected. They have their same character skillset, except they hunger for flesh, and tend to be a little more...slow. They however can die if struck with their living weakness. Ex. deku undead will die in fire. This keeps going till all but one person is infected. Then the calvery comes to save the day!
I'll post maps of the area, buildings, and supplies prior to the match so you know what's at you disposale. Just the players cannot leave the playing field. Oh and yes if you have multiple characters like eric, then u can use more than one, but only do as many as you can handle.
PS. Fighting style goes like in the arena, everyone gets a chance to dodge.
PSS. These matches can drag on so in game time day's may pass with little supplies, I hope you play your characters accordingly. lol.
