Just a thought on some possible new games modes to mix it up.
As a Fireteam if you miss the exfil chopper it should continue a new game that’s more like the last act of predator where the predator looses his mask & cloak and is limited to only his wristblade and the Fireteam member also has most of his weapons removed except for a knife and a crude bow with limited ammo the environment should be dark with traps laid out. Another idea as you seem to be continuing the story from The predator would be a game mode with allied predator versus a super or ultimate predator it is something I was interested to see in the last film so it was sad to see it get cut.
Just while we are on about new content please include the Celtic and the wolf mask from the AVP films as mediocre as those films where the predator designs where pretty cool
