So it is for my Gears of war map, I want to use burrowed units to detect if a player is behind cover, and I will make two locations follow each player: One 2.5*2.5 location and one 1*1. If the burrowed unit is in the 1*1, the player is totally invinsible, but if the burrowed unit is in the 2.5*2.5, I want the player to be vulnerable to around 50% of the hits...

I got my own Idea but it is going to need another computer player, lowering my enemy comptuers from 6 to 5, since I am not too good with multi unit vHP it is going to be hard to make tough enemies...

I got 6 computers that are enemies to the players and the 2 other slots are the players.
