The C12 is a bipedal 12-foot drone tank featured in Call of Duty: Infinite Warfare. It can operate in autonomous or semi-autonomous modes.
The C12 is a large bipedal drone, armed with a variety of heavy weapons. The C12 has a set of dual missile launchers on its right shoulder and a high-calibre minigun on its left. It also possesses a top-mounted cannon, though this is not used in gameplay. The robot possesses two arms equipped with manipulators and is quite strong; it is capable of battering open heavy metal doors with ease and even partially lifting an infantry fighting vehicle off of the ground, as well as even being able to wrestle with other C12s. The C12 is also quite durable, being immune to small arms fire and capable of withstanding numerous missile hits. Despite it's size, the C12s multiple degrees of movement allow it to curl up during transportation and fit within the hull of a Raven transport.
Many more C12s are seen throughout the campaign, used mainly by SetDef. In "Operation Burn Water", a C12 is deployed to Titan to assist Reyes and Omar's team in clearing out a SetDef-controlled station.
The C12 makes its final appearance in the last campaign mission, "Operation Blood Storm", where one unit is seen killing Maynard "Griff" Griffin and several other soldiers as they defend the remaining crew of the Retribution.
A player may destroy it in one of the three ways, and if the player manages to do so in one go of campaign, unlocks the C12 achievement.
- Left Rodeo: The player destroy the Missile Launcher on the right shoulder, the player may jump onto the bot and rip its minigun, firing it on the bot's head and destroying it. However, the player will take damage as they fire, and if they failed to destroy the bot, they will die.
- Right Rodeo: The player destroy the Minigun on the left shoulder, and jumps onto the bot. The player rips out one of its missile, and jam it into the bot's body. The player then detaches from the bot and try to fire on the missile, exploding it and destroy the bot. Failure to destroy the missile will make the player continue fighting the bot, but the missile can be shot down at any time afterwards.
- Blowing off multiple limbs: The player simply destroy both weapons, Minigun and Missile Launcher, from a distance.
