I use tdm 'dominion' or 'mission08' outfit to convert it on a 12 players mp coop.
This map as 4 objectives similar to 'coop_youppi' the difference are that I had 1 tank at the third obj.. and one chopper(mi28) at the end.
And it's a night map with 4 different sky changes like it begins at midnight to finish at 5 am.
This is a multi-spawn map for 12 players at the end you have 2 snipers that are hiding in the building where's black smoke behind school bus.You don't need to destroy the chopper(mi28) to end match.
Installation:Unrar into GRAW2 cutom_levels folder.
