Zombie Army 4 Gas Rats
In the video above, you can see where to find the five gas rats.
The first rat is sitting on top of a missile in the middle of the first area, suspended high above. As you exit the safe room, look to the middle and on top of the missile.
Next, go through the door the Butcher breaks through and go around to where the Upgrade Kit is. Look at the pipe on the left wall. The second rat is on the pipe.
After you break the second and third valves and drop down, walk through the deep water and once you’re out, stay on the left and you’ll find the third rat on a pile of pipes.
Once you reach the area with the final three valves, stand near the sealed door and look in the direction left of the door, towards machinery. Look for a red flashing light. The rat is hidden behind the machinery and is all the way back towards the wall.
The final rat is sitting outside the safe room on some crates.
After you kill all five gas rats, go into the safe room and when you regain control, you’ll be able to get the contents of the safe; a divine attachment and divine grenades.
