Big team battle and flood mode

Anyone know how to create a map where it is a big team battle but also with one player as flood ? The two teams fight but the flood guy goes around and kills players slowly growing until both sides are done and flood wins or time runs out.

Seems legit.
i like the sound of that.
Youd have to go into game options though.
the map wont matter

I like this. Makes way more sense than regular infection mode or flood mode.

If you get this going, please send me a FR and invite to some games.

With the current limits of customs I don’t see how this would be possible unless you went back to halo 2 style zombies and had a 3 team slayer game with a trust system going where if you are killed by the zombie(flood), you have to change teams.
