The apocalypse has begun.
—Apocalypse Tank

The Apocalypse Tank is a Soviet stolen tech unit acquired by infiltrating any of the rogue Soviet labs and Construction Yard. The most powerful tank the Soviet Union have to offer, this unstoppable juggernaut is armed with Tesla cannons and missiles to sweep away anything in its path.

It did not help the Soviet enemies that the Apocalypse Tank can also periodically heal nearby friendly infantry and is more resistant to EMP weapons.

Official description

During the late stages of the Second Great War, conventional heavy tanks proved useless in countering the versatile aircraft and nimble tanks of the Allies, as they were gaining the upper hand over the Soviets. In response, the Soviet engineers set out to design a truly unstoppable tank. Unexpectedly, the Soviets lost the war before this "super tank" could be produced. The blueprints for the vehicle were quickly hidden, and all prototypes were destroyed to prevent the Allies from stealing the project. Then, once the Soviets were free from the Allied occupation, the idea of a 'super tank' resurfaced. Renewed work progressed steadily, and soon after, the tank was ready to be unleashed from factories all over the Soviet Union.

However, in the end it turned out that the tank, now called the Apocalypse, was not very cost-efficient. Even with its amazing firepower and reasonable mobility, the modern successor to the Tesla Tank, the Tesla Cruiser, and even the Latin Confederation's budget version of this 'super tank', the Catastrophe, proved to be much more effective in battle for the price required. Thus, the Apocalypse was reluctantly retired. While some can still be found in larger Soviet bases, the tank is no longer in active production. Some of the Soviet generals still keep a few units around for the nostalgia factor, and the symbolic importance of the vehicle. Rumours say some of the remote-controlled models are still kept somewhere.

The Apocalypse Tank is equipped with twin 125mm Tesla-enhanced cannons, which are lethal to all that stand in its path, and the unit's many "Mammoth Tusk" missile pods make this monstrous machine a viable threat to aircraft and infantry alike. The idea of "throwing everything you have at your opponent" is well-represented by the Apocalypse, as it will use all of its weapons at once against the enemy. Due to its turret's excellent design, the Apocalypse Tank can fire while on the move without losing much accuracy.[1]

THE ultimate assault unit in game, the Apocalypse is not to be trifled with. Extremely durable and equipped with its powerful 125mm cannons, the Apocalypse is able to take down anything that resides on the ground. The tank is able to shoot while on the move and has an impressive range on its cannons, able to outrange most units/base defenses. With its somewhat average speed, it is able to kite some units the same tier as itself. The Overcharge ability (only available to the Russians) can enhance the tank's firepower by 50%, allowing it to destroy stronger foes with ease.

Occasionally, the tank will use its Mammoth Tusk missiles on ground units, which is extremely effective on buildings and vehicles. And if that's not enough, the Apocalypse is able to use its missiles to take out even the biggest targets in the skies, making the Apocalypse one of the biggest threats to air units. This quirk makes the Apocalypse a good defense unit as well.

In addition, the Apocalypse periodically heals infantry units around it with its healing aura. This allows the Apocalypse to support infantry rushes as well. Another impressive quirk is that the Apocalypse is much more resistant to EMP weapons than other units in game. EMP duration is halved for the Apocalypse, making the Tank extremely durable against rogue Soviet opponents with EMP weaponry.

However, even this monstrosity of a tank has some drawbacks. Being a stolen tech unit, it might be extremely difficult to acquire if the Soviet general's enemies are extremely careful with their Soviet lab and ConYard. It costs $2000 ($1500 with Industrial Plant), the same with every stolen tech unit. The Apocalypse is susceptible to mind control, hijacking and confusion rays, enhancing the fact that the Soviet general must take very careful measures against Epsilon and the Foehn Revolt.

Weapon stages

The Apocalypse Tank uses a weapon cycle that allows it to fire different weapons on the same target. It always starts at the cannons once it switches targets.

  • Stage 1: Lasts until 200 frames (13.3 in-game seconds). In other words, the Apocalypse Tank will attack thrice with the cannon.
  • Stage 2-3: Lasts until 340 frames (22.7 in-game seconds). In other words, the Apocalypse Tank will rapidly launch six instances of missiles at ground targets. Once Stage 3 ends, the cycle repeats. For more details, Stage 2 lasts until 300 frames (20 in-game seconds) while Stage 3 lasts until 340 frames (22.7 in-game seconds).

Unlike other Stolen Tech units, Apocalypse Tank is more common in missions, and players can control a limited number of them in some missions, and even buildable in two of them. Due to the large number of appearances, only the special appearances are listed below.

The player is available to use a limited number of Apocalypse Tanks in Thunder God, Dragonstorm, The Raven, Juggernaut, Power Hunger, Earthrise, Brothers in Arms and Fatal Impact.

Act Two

  • In The Conqueror, an Apocalypse leads the Soviet military parade in the city of Moscow. Two other Apocalypses are in the ranks of the Black Guard protecting the Kremlin and Alexander Romanov.
  • In Meltdown, each Epsilon Rocket Launchpad is guarded by an Apocalypse.
  • In Relentless, Yuri has access to a few Apocalypses, which he'll send against the Allies after the Psychic Beacon is destroyed.
  • In Death's Hand, the Apocalypse Tank is unlocked by any Soviet Tier 3 acess structure.
  • In Withershins, the Epsilon Army has a few Apocalypse Tanks at their disposal.
  • In Hamartia, the Epsilon defenders will once again employ a limited Apocalypse Tanks as a part of their arsenal. More will be show up once the mind-controlled Soviet forces arrive to assist their new masters.
  • In Babel, the Allies have access to some Apocalypse Tanks that were abducted via Chrono Prisons.


  • In The Great Beyond, each Epsilon outpost on the islands designated to be the potential locations of the Foehn secondary base is guarded by an Apocalypse.

Special Ops

  • In Dawnbreaker, after the manufacturing complex is restored and the blueprints in Palace is protected, the Apocalypse will become buildable, marking the first time where a stolen tech unit is buildable in the campaign.
  • In Brothers in Arms, a special Apocalypse Prototype is located at top left of map. The player needs to capture a special Technician through Drakuv Prison Vehicle, to operate it. See here for its details.




  • Extremely powerful against all units.
  • Can defend itself well from air units.
  • Extremely durable.
  • Immune to omnicrush.
  • Can crush infantry.
  • Can fire on the move.
  • Heals nearby friendly infantry periodically. Healing effect stacks.
  • EMP weapons only affect it for half the normal duration.
  • Can self-repair.
  • Using Overcharge on the Apocalypse Tank can temporarily increase its firepower.
  • Expensive ($2000), but with the use of Industrial Plant, it become $1500 which is a very reasonable price.
  • Late game unit, only available after building and infiltrating a Soviet lab and ConYard.
  • Susceptible to mind control, hijacking and confusion rays.
  • Below-average speed.
  • Self-repairs cannot sustain it when overwhelmed by anti-armor fire.

Behind the scenes

  • In version 3.0, the Apocalypse Tank was $200 more expensive than now but much weaker. It also did not have the healing aura. This is also the only stolen tech unit from v3.0 that has the exact same prerequisites in v3.3.x, although Science Lab is replaced by Atomheart.
  • Interestingly, the Apocalypse Tank from the 3.x series takes the internal name (MAMM) of the Mammoth Tank from older versions, while the Catastrophe Tank takes the internal name (APOC) of the Apocalypse Tank from older versions. Given this, it is possible that the Catastrophe Tank was supposed to replace the Apocalypse Tank for good at one point, and the (re)inclusion of the latter was an afterthought.
  • The Apocalypse Tank in pre-3.0 versions of Mental Omega had the ability to crush smaller vehicles.
  • The original Apocalypse Tank voxel used by Mental Omega is a public asset and can be used by other modders. The link can be found here.


  • When the Apocalypse is affected by Overcharge, this also increases the firepower of its missiles, which is noticeable against air units. This is illogical as the missiles are not Tesla technology.
    • Since 3.3.6, this is no longer the case.
  • Even though the Apocalypse Tank's main weapon is classified as Tesla technology, it does not cause the Wormqueen to repair itself.
