It could be an interesting new gameplay mode.
Location: a map like the final stage of evac mode. Local fauna attacks, more dangerous animals as the match progresses.
Monster level 1, he can’t evolve, he can’t backtrack to a safe area to feed, he can try to feed in the area if hunters allow him. When he dies a monster level 2 will spawn, same mechanic. Finally a monster level 3.
Hunters get money with kills, they can invest the money in turrets, barricades, devices to slow down enemies, defend the tower stuff. Hunters have a limited number of spawns.
Match ends if they kill the monster level 3 or resist until the evacuation ship arrives…or monster kill them.
