The machine known as V2 stands as a formidable early antagonist and a direct counterpart to V1 within the brutal world of Ultrakill. Bearing a near-identical chassis to the protagonist, distinguished only by the "V2" marking, it presents a stark reflection of the player's own capabilities. First encountered as the overseer of Limbo, V2 acts as a crucial proving ground, demanding mastery of dynamic movement, resource management, and diverse weaponry. Its combat repertoire echoes V1's, showcasing familiar firearms like revolvers and shotguns, yet deployed with unique tactical nuances. This nascent rivalry intensifies in the depths of Greed, where V2 seeks retribution for a pilfered appendage. Despite its implied superiority as a later iteration, V2 ultimately succumbs to V1's relentless aggression and adaptability in both confrontations, underscoring the latter's desperate and ultimately more potent thirst for survival.
