Yes, the Nothern Strike map conversions have full coop/sp support (16, 32 & 64), but the installer will only set up the coop/sp support if the booster pack is installed.
Agreed it does ROCK! Especially since it seems your updates are more frequent than the multiplayer leg of the mod. At least we have 8-10 maps to play with singleplayer instead of 5 maps.
ummm.... I dont know if this is a problem, but I do not have Northern Strike, but the installer thinks that I do? Is this supposed to happen? and will it screw up 2142/ First Strike if I install it with the northern strike map support included?
