The fireteam becomes aliens who’s goal is to Harvest/kill all the AI or of course kill the predator or harvest it to make a predailen(bonus exp like capturing the body for OWLF) for the hive.
The predator has to find the aliens and kill them at which point it is free to destroy the hive with it’s nuke thus winning the game. Should it fail and is put in second wind it is vulnerable to be harvested it can still heal or choose to arm the nuke.
But the aliens will be given respawns based on how many AI they have harvested(alien health will be lower to compensate for this and each respawn increases the timer meaning the predator is able to cycle for enough time to destroy the hive.)
This is a rough idea for a game mode any input or changes that you think would make the mode more entertaining and balanced are welcome.
