Sisyphus Prime (P-2) Strategy

Conquer Sisyphus Prime in ULTRAKILL's P-2 level. This guide details multi-phase tactics, aiming precision, and mastering Sisyphus' hammer attacks.

Sisyphus Prime, the final boss of the P-2 level, is a true test of your ULTRAKILL mastery. This multi-phase encounter demands impeccable movement, precise aiming, and a deep understanding of your arsenal. Prepare for a relentless onslaught that will push your skills to their absolute limit.

Phase 1: The Ground Game

• Sisyphus will primarily use his hammer for devastating ground slams and sweeping attacks. The key here is to maintain distance and use your dash and slide to weave through his predictable, yet powerful, swings.
• His projectile attacks are relatively slow but can be overwhelming in numbers. The Malicious Railcannon's charged shot is excellent for interrupting his attacks and dealing significant damage.
• Don't underestimate the importance of parrying. A well-timed parry on his hammer swings can stun him, opening him up for a barrage of damage. Experiment with the timing; it's crucial.
• The Sawblade Launcher can be surprisingly effective for consistent chip damage and for clearing out any smaller enemies that might spawn.

Phase 2: The Aerial Assault

• Sisyphus will begin to incorporate aerial attacks, leaping and slamming down with his hammer. This is where your verticality and air control become paramount.
• Use your rocket jumps and double jumps to stay mobile and avoid his downward strikes. The Rocket Launcher is your best friend here for dealing damage while airborne.
• He will also start using his signature move: the "Sisyphus Slam," where he charges up a massive area-of-effect attack. You'll need to find cover or perfectly time a dash to escape the blast radius.
• The Knuckleblaster's secondary fire can be used to propel yourself upwards, allowing you to get above him and rain down rockets.

Phase 3: The Desperation Dance

• In his final phase, Sisyphus becomes more aggressive, chaining attacks and increasing the frequency of his special moves.
• This is where you need to be at your most efficient. Focus on landing consistent damage with your strongest weapons, like the Malicious Railcannon and the Rocket Launcher.
• Don't be afraid to use your Blood-Fueled abilities if you're confident in your ability to survive the immediate aftermath.
• The most important advice: stay calm. Panicking will lead to mistakes. Observe his patterns, react accordingly, and keep the pressure on. Victory is within reach with persistence and a solid understanding of his moveset.
