In Skirmish mode, we don’t have to worry about units or base building; players start with their default loadout, and it’s up to them to handle the rest. All we need to do is add the start points. Click two of them down and return using the Selection tool. From the first, choose Player_1_Start, for the second… well, take a guess. Normally you’d want them more spaced out, but we’re on a small map here. Finally, open Edit >Player List, and click Add Skirmish Players.
