I have a mountainous area in my map in which I plan to have two small sects warring. There's a little base on the right side of the area and a cave on the left side, and basically I want to have a marine spawn at each occasionally and meet up with the enemy marine somewhere in the middle. It should be a simple thing, but unfortunately the alliances in my map don't agree. Players 1-4 in my map are all human players. Players 5-8 are computer players. Players 5 and 6 are allied to the human players and to each other, but enemies with players 7-8. The generic enemies in the area (you know, the ones you run into in every rpg that tend to be stupid things like a zergling named "wolf" and whatnot) are owned by player 8, and the human players have vision with player 6. So the logical thing would be to make one rine for p5 and one rine for p7, but the generic enemies will then attack the p5 marine and the p7 one will always win. I need help trying to figure out a way to have little battles independant of the regular enemies, without the human players having vision of the battle.
Thanks!

Just make Player 8 allied to Player 5?

How simple and easy that would be. Unfortunately I can't.

Use the Order action to keep the generic enemies away from the marines.

Or make P5'S marine stronger.
