SAS Soldiers are placeable units in SAS Zombie Assault Tower Defense that can be used to fight the zombies. The player can chose from between either Machine Gunners or Snipers by placing them on rooftops or the streets. When knocked out of commission, they let out a loud yell which can notify the player that a SAS Soldier has been knocked out.

Machine Gun SAS


The MG SAS is a very useful unit to place on both rooftops and the ground. Place them in corners or high traffic areas to soften up zombies for your main guns. While weak to begin with, an MG with a Grendel and three freeze grenades can take a Ruin out by himself.

Tips and Tricks

It's important to remember that if you place any SAS unit on the ground, all zombies will attack them as they pass by. This can be helpful because you can place them off to the side of your paths as roadblocks or distractions.
