You will have noticed by now that missions 1 and 2 both include both Blood Angels and Space Wolves. These missions are incredibly fun to play three player (one stealer player and two marine players.) The rules for doing so follow.
- You share command points and must agree between you how many each of you gets each turn. If either sergeant dies, control of command points will fall to the player with a living sergeant. If both die, you go back to having to fight it out over who has control.
- Both players move their marines inside the same phase. The time limit remains the same and when that time is up, play turns over to the Genestealer player.
That pretty much covers it.
