Do you guys want me to set up Alien Containment again (same sides)? According to the mission description, the only side that should be destroying computers is Marsec; the Rebels are defending them and the Aliens are simply trying to get the hell out (move to the edge of the map and select Escape). So another side destroying computers meant that Marsec won by default.
If I don't hear back by Monday I'll set up the next three-player mission.
