Who is creator? Can you told him that he can make both modes in one map? There is not necessary to create two maps, same maps, each with different game script only.
=SEF= Clan doesn't play coop, Seb (not sure) made it.
Exper made a coop version for it.
Shogun makes a new version with a pilot, based on [JPV]XXX script.
More details :
Weapons don't disappear.
Collision to avoid "over-the-wall" nades.
Agressive AI.
More waypoints.
Pilot is medic.
Medkits at start.
New lightmaps.
Edited fog,background,world sector
Added events (nothing loud)
The coop has been created to be fluid so there is a certain gameflow.
Very stable, no bug.
