The Tank

The Tank is an special infected that was added in 1.3.1

The Tank is a very dangerous type of infected. Despite its bulky looks, it can keep up with the player and other survivors.

The Tank has the same speed of the Sprinter perk. Players without the Sprinter perk will fall victim to it.

It deals the same damage as normal infected. (Not confirmed)

It'll spawn at some military bases and fire stations, however spawning chance is very low. (Confirmed)

Combat Tips
If you are inside a building, the Tank will run around the building, occasionally hitting it. It will wait for you to come out. Sometimes, it will stop and rest, giving you a chance to attack it while it's down.

When engaging the Tank on the move, you can try shooting him, but it is not entirely recommend unless it's your only alternative. You can hide in any available shelter (including a bus) and use melee weapons. A Hatchet or the Fire Axe are most effective. When the Tank is near the door, charge at him and then go back and wait, letting you save your bullets

Trivia
• The appearances might be resembles to the Tank from Left 4 Dead with the same name, except it doesn't throw concrete/rocks at the player.

• As even the enemy itself is strong and looks like a bullet-sponge, it is surprisingly weak. .45 ACP and 9mm pistols can take out a good chunk of its health away

• When you kill it with a firearm/sidearm, it will sometimes drop ammo for that gun.
