As much as I like to play flood, some things need to be changed and, or, maybe added.
1) Flood need to be able to use weapons other than their sword arm thing for games like duck hunt (sniper) and fat kid (hammer).
2) Flood load outs need to be able to be edited like the base player load outs so people can edit the equipment they use.
3) Proximity chat needs to be put back into the game. How else will I scare the crap out of my friends?
4) Allow survivors to have their own colors not the ugly green color (unless that's their favorite color in the world).
Something I just remembered, there is a problem in flood matchmaking. When host migration takes place and then finishes, if you're human, you can kill other human players and it will turn them into the flood. IT'S A PILE OF DOODY WITH SUPER LAME SAUCE ON THE SIDE!
This is what I feel should be put into this here game type. If anyone feels like adding something go for it.
