8 Fireteam players and 2 Predator players.
Split the FT into 2 opposing teams of four in a domination style match type. The fire teams will fight over an objective that needs to be secured and then extracted by helicopter. The objective wouldn’t be available immediately, and its location would be random providing the opportunity to hunt the opposing team.
Once the objective is complete, the winning side will need to make it to a separate location to meet up with da chopper. The opposing team can prevent their escape by either killing them or by giving up their position to the predators. If they succeed in preventing their extraction it becomes a team deathmatch scenario with the last team standing being able to call da chopper for extraction at the same location.
Additional XP/veritanium would be earned by the team that gets a clean sweep by completing the objective and getting safely to da chopper.
Predators can win by eliminating the fireteams or by destroying the objective. This would prevent both fireteams teaming up to hunt the predators as a certain number of FT members would need to stay and defend. The predators are on the same side although compete for XP with the top dog getting bonus XP and veritanium.
