As we all know PC Gamers are capable of doing many things.

As I'm watching some videos of hunter mode this idea of co-op came to mind. How about getting some modders to make some maps that would have only 2 (default) amount of hunters and not get any more. For the CELL, 4 may be decent.

A small group of CELL was ambushed and forced into a cave or a building of some sort and there is no way out but forward. Most if not all the maps are a bit tall so the hunters can jump around, go through vents to kill the CELL operatives, whereas the CELL are trying to reach the exit of the cave or building successfully without dying.
If any CELL units die, they spectate their teammates until a checkpoint is reached.

This idea is just a rough copy that I just thought out from my head a few minutes ago, but hey if you dont let your ideas out they may never be thought of ever again.

Feel free to add any suggestions to this co-op hunter mode that may be added in the future of Crysis 3!

Sounds awesome, but if the hunters use the bow, it would be pretty overpowered.

What about when Hunters die?
