It uses radiological, biological and chemical weapons just like the Apocalypse Class machines utilize but also comes equipped with special shield emitters that negate all form of damage while active and also utilizes a very powerful, custom crafted thermobaric weapon when posed with a major threat. It is unconfirmed that the NBC-type weapons were added as part of FNIX's overhaul, as they are similar to the Apocalypse Class machines. FOA 2 had come up with the code name for that prototype of a beefed-up Tank: 'Liemannen' (Swedish for 'the Grim Reaper'). 'According to the digital blueprint, this iteration of the Stridsmaskin 90 seemed to have been completed by FNIX itself, it is likely shortly before the Cataclysm happened, FNIX took over and started overhauling an unfinished top secret prototype project taking place in the secret FOA 2 facility near the Norrmyra base. Spawned like a Rival, its level will always display '?'. It also has four shield generators displayed as red glowing bumps on both shoulders and the sides of both knee joints. Its abilities include those of previous tank versions combined with its ultimate attack, the Thermobaric Explosion. Its look is based on the common Tank, but with heavier armor plating and orange wires.
The strongest of all enemies, the Reaper Tank is the latest addition to FNIX's army.
