It heals your broken limbs but as everyone has said is hell to get to.
I highly recommend going to a gas station if you want to get your arm fixed. Why? The road maps will help point out hospitals (or other areas) and a pile of Molotov’s can be used to clear it out. [B]DO NOT USE THEM INSIDE![/B]
-Bring something noisy to the hospital (Truck with no muffler, guns, grenade, exc.)
-Make a lot of noise to stir up the hornets nest.
-wait out front (or back, or anywhere they can get to you) for the hoard to arrive.
-Use Molotov’s to make a wall of fire and let all the zombies burn trying to get you.
-???
-Profit!
