Unit 0

"Someone had to take care of the business, order will be restored. The agency is no longer in charge." -Jeremotas, on his Newgrounds pageThe organization falls under the control of the Auditor. Under the Auditor's direction, new ranks within the organization were initiated. They have multiple weapons and vehicles and were allies of the AAHW before turning on them and killing them.
== Units ==
=== Unit 0 Agents ===
Unit 0 Agents look like normal A.A.H.W agents, but now have more yellow to their original business suits. They also sport black sunglasses. They sometimes have some armor, like helmets and bulletproof vests. Like the original agents, they excel at being versatile in combat, being able to handle a multitude of different weapons, ranging from blades, to shotguns and assault rifles and often come in large numbers. 
=== Unit 0 Mercenaries ===
There are many types of Unit 0 mercenaries. They sometimes sport a balaclava or a gas mask. They sometimes have bulletproof armor, and are more skilled than the normal Agents. They have a variety of weapons, but some of the most notable types are:
# Balaclava Mercenaries: These have a balaclava/ski mask with holes for their eyes and mouth. Some have OBSV goggles like ATP Soldats, and they get their new missions from their goggles. Some just have yellow goggles to block their eyes.
# Gas Mask Mercenaries: These have a gas mask and usually some other armor. They carry medium to heavy weapons and are probably able to breathe through bad gasses. Some carry grenade launchers, as seen as one shoots one into a building to enter it. They wear the same suits agents wear, too.
# Radio Mercenaries: Only one was seen in the end of Madness Combat 5 Remake, tapping on his radio headset and running off with another Mercenary with a gas mask. He seems to be one of the members in the "squad" that the Unit 0 officer mentions.
=== Unit 0 Medics ===
Unit 0 medics sport a utility vest for holding medical supplies. They usually have a mask that covers their entire face and is transparent. They have medkits to help their wounded comrades, but also have little weapons like pistols in case of an attack.
=== Unit 0 Tank ===
Only one tank has been seen. They have a helmet that covers their entire head, and have goggles that look like engineer goggles. They have heavy armour and a heavy machine gun. He is seen in district 14 with other Unit 0 Mercenaries. However, after he enters a laboratory with some sort of failed experiment in nECRO-CORP Sla, he takes down a few zombies before getting killed by a very large one. He seems to have been mutilated badly, with large chunks of his flesh torn out by the half-mag zombie.
=== Unit 0 Officer ===
Same as the tank instance, there is only one officer. At the end of Madness Combat 5 Remake, he is seen talking to the Auditor, saying "Yes...everyone is dead." (He is probably talking about the AAHW getting massacred by Hank.) The Auditor responds to him asking if the squad was deployed yet. The officer confirms saying that they are looking for the interloper, and the video ends from there. The Unit 0 Officer seems to be a Unit 0 MERC with a bug-eyed gas mask. He could be seen in one of the ads on the buildings in Madness Combat 5 remake. He seems to be an important figure in Unit 0, because so few only actually talk with the Auditor in person.
=== Unit 0 Futuristic Trooper ===
The Futuristic Trooper is a special character only seen once. He was stationed outside of the failed laboratory while another agent went inside. He has a futuristic side in his armour, with a new improved helmet and some fancy armour. He wields a SMG and probably has more weapons that we don't see too.
