Like the title suggests,
It would start as a regular mission, your making your way to the objective, then there would be hanging bodies everywhere, one falls and draws your attention then you hear the Predator, it then shoots plasma from a tree top and you take cover, it appears and melees one of the A.I team members, you watch in horror as it claims animation it and you shoot but it vanishes (not cloaked then jumps away just spawns, melee/claim animation and cloaks and despawns) you then noticed the green luminescent blood and it trailing deeper into the jungle, you follow the trail near the river, where there you hear it medkit animation then roars, it then noticed you and jumps and vanishes, you then go back to the objective and there it attacks you, the phases would be plasma phase (plasmas and vanishes) melee phase (melees your team members and you have to shoot it and if it downs them all you lose) then the explosive barrels phase (it tries to attack you and you shoot red barrels around it) then it activates its Bomb (you are not supposed to disarm it but if you do you get a achievement and forced to defend it from waves of A.I until the timer runs out) afterwards then you get a cutscene of Zeus (about time we see him) coming down in a chopper and he recruits you into Dutch’s team, where he makes a appearance smoking in the chopper as you board, he nods in acknowledgment and offers you a cigar.
