Game mode Idea:
Ability to invite your friend or randoms to a PvP death-match.
You start out with 3 random characters. You're able to choose 3 from a pool. (These are separate from your saved game and no consequences.)
You a have a mini base on a mini map. (large enough you cannot snipe across it)
Your storage locker is equipped with a set amount of supplies. You can choose to craft weapons and equipment until you run out.
There will still be loot-able buildings so you can find more weapons or ammo during battle.
You have approx 5min to prepare for battle with a countdown. (or choose to ready-up sooner)
When battle begins, you have to eliminate the other team (one player and two bots) . Zombies can be used against them by throwing distractions or zombait etc. hordes, juggs etc can intervene.
Maybe play a best of 3?
