Set up a custom match with at least one strike and two minutes dropship time and invite a friend to be the monster. Have him kill 2 of the bots or let the wild life kill you and take over one of the bots and repeat. When there is two characters left the monster lets you drain his health til he's nearly dead and then you let him incapacitate you and then hopefully you can deal the final damage before the bot who is left.
Even easier if you are a team of 3-5 so the hunters can help deal right amount of damage and then stop so you can deal the final damage.
Or you can do it in Defend mode and the monster can kill the other three hunters to be sure no one other than you kills him. Set the dropship time to 2 min and meet up away from the generator and turrets.
