I’m looking for a coop real time strategy game that allows this:
- Two players start a networked game, against each other,
- Later, additional players may join the game, on a side of their choosing. Then
- all players on each team can control all units etc. independently and simultaneously.
Preferably it should be Free Software and runnable on Linux.
Does such a game exist? If not, what free RTS would likely be easiest to patch to support that?
