im taking this from another multiplayer game where you could do offline co op or solo missions once every 24 hours
the idea is to actually implement an offline mode that everyone wants but without actually killing the multiplayer player base
fireteam 4/3/2/ or solo (can be done with any number of players) same as the current one but with some handicaps (that game made this available but it gave you some restrictions in your loadout and enviroment so it was actually fun )
predator almost the same
