Krazy Ivan , a game about saving the Earth from alien invaders, tells the story of Commander Ivan Popovich, aka "Krazy Ivan", a paranoid schizophrenic with a talent for violence. He must stop the aliens from erecting energy generators across five areas of the planet, which are slowly encasing the entire surface in a field.
The gameplay revolves around controlling Ivan's Steel Cossack power suit on 3D battlefields, where two types of enemies can be found: Drones and Sentients. Eliminating each Sentinel is crucial to destroying the energy field generators and completing missions. The Cossack can carry various weapons, including projectile and energy guns, missiles, and special items.
As players progress through the game, they can upgrade the Cossack with more powerful weapons and replace its armor after successful missions. Additionally, rescuing captured humans and collecting power-ups will aid in Ivan's quest to save humanity.
The game features live-action cutscenes between missions, showcasing Ivan's journey and the humorous side of his story. These scenes are accompanied by English actors with thick Russian accents, adding a comedic touch to the game.
