I cannot find anything about player numbers, having seen 64 player CS games I'm assuming that may be an upper limit. Anyone have any info ?
Ah, found some more concrete answer to this...
Insurgency Wiki said:The current feature being worked on, that will most likely be the one in release, includes 2 potential squads for each team (8 players in a squad).
That'll make for 16v16 games, i.e. a 32 player server.
