[PC][1990] Post-apocalyptic robot spheres

Platform(s): PC

Genre: First person (maybe 3rd) RPGish/upgrader (Don't think there was any xp, just money and gear/chassis upgrading)

Estimated year of release: 199X

Graphics/art style: Quake Arena style graphics but outdoor settings - jungles, deserts, plains, chasms, mountains etc. Can't remember if post apocalyptic or dystopian or alternate earth

Notable characters: You play an AI in a robotic tank-like spheroid body. Thare are other AI and factions but all in the same kind of tanks. I think every city is a computercore

Notable gameplay mechanics: You could trade resource and upgrade your chassis, equipment or weapons, but alwasy stuck in a robotic sphere. It reminded me of hard truck:apocalypse in the gameplay mechanics and quests. I think there are quests but can't really remember. It had bad translation from russian or a likewise language. There was also a sequel.

Edit - eventually remembered a couple of minutes after post
