The Tank (in-game name KK-Tankki) is an enemy that appears to be a minigun on tank tracks. It moves slowly and is unable to jump, but it boasts a lot of firepower. If it sees the player, it will slowly rotate its barrel to face them and begin firing. It shoots bullets at a high rate of fire with low accuracy. Like all bullets in the game, they will interrupt levitation for a moment if the player it hit. If the player is cornered against a wall, they may end up being stuck there until they die or the Tankki is destroyed at the cost of a considerable amount of health.
Like most ranged enemies, it will not fire without a line of sight. It will not chase the player and is too slow to do so. It has a blue light on it that reveals its location, even in undiscovered areas. The turret has a slow enough traversal speed that the player may be able to fly over it and destroy it before it can get off a shot. Its death explosion is quite large and will ignite flammable material, which is often the large amounts of oil it bleeds. This can make gold collection difficult. Killing it with a rapid, low damage wand appears to produce more oil over time.
It is resistant to many forms of damage, especially slice damage, taking no more than 1-3 damage per hit for most spells. Explosions and electricity are effective, though both are often costly to use or hard to acquire.
The KK-Tankki seems to be the most common tank, with several of them in the same room occasionally in the Hiisi Base. In the Snowy Depths a structure may generate with a wooden background and steel and wood walls. This may generate with 3-4 KK-Tankkis inside it. The next common tank is the IT-Tankki, and the rarest is the Laser-Tankki.
