if your confused about the 4 commands, fall back and assault apply to all units regardless of what is selected, including units that havent spawned yet. the inner 2 apply to your selected units.
I was in the top 5 for the first few weeks with my score of 74 on ninjakiwi.com without using the mochicheats. you really don't need them at all, imo they just ruin the game.
The special mission which has the green zombies that come out of a portal is glitched after the 2nd portal. The 3rd never comes and you cant finish the mission, just a zombieless screen and the mission guy tellin you to figure out how to kill them.
Has anyone finished this mission?
