CO-OPs are only restrictions in CoD's mp-environment.
It is possible if one put on a server with ki-targets and no side-switching and plane-changing allowed.
Why this could be desirable, beside delivering easy ki-targets to kill, is beyond me.
CoD gives the freedom to have all together, the online war, human and ki opponents and even ki comrades to fill missing slots.
It is just that someone with the knowledge has to program the mission, i dont think that there is a already established server that wouldn't run it.
