The Monster Face is the 25th head armor in the game. It was called simply Zombie and was part of the Bio Hazard (Bundle) before it had a remake during the Halloween 2014 update, where it was renamed and became part of the Monster Gear.
Before Halloween 2014 it was unlocked at level 27 and provided 5% health. The description said "Brainnnnnns dude!"
During Halloween 2014 it got an update, now it provides 5% health and has a special ability which increases 40% the damage when carrying Monster tagged weapons. In this case, the Toxic Guns or the Darkness Combo Guns also get this bonus damage. Also, it has no level requirement anymore and it can be achieved by beating various tiers in the Monster Mash. The description was changed as well.
A battered green steel helmet with brain protruding from the back. The chin strap is loosely hanging. Its most noticeable feature is a machete wedged in the helmet. The wearer's head is changed to a bluish, decayed head with yellow eyes and a neck brace covers the wearer's neck region. The eyes also take on a purple hue. Two teeth stick out from the monster's mouth as well.
- It was part of the Bio Hazard (Bundle) (although the bundle is now known as Monster Gear).
- Bio Hazard (the elite who wields the Blunderbuss) always uses this along with the Monster Vest and Monster Pants.
- You can't buy this in the shop with anymore. Thus, the only current way to obtain it is through either a Halloween-themed event or by pursuing the said bundle from above.
