Genocyber (1994)

In the future, the nations of the world begin to unite in peace. Soon, however, this peace is threatened by private armies of individual corporations. One group in particular, the Kuryu, discovers a weapon of mass destruction that could tip the balance of the world in their favour: a combination of cybernetics and psychic potential straight out of a nightmare. The weapon is known as the Genocyber. Many other corporations want it too, but can they contain it before everything is baked in violence? This anime is particulary known as one of the most goriest and gruesome anime ever produced.
