the Parry mechanic is a vital component to ULTRAKILL's combat that can save V1 from certain defeat by turning the attacks of his foes against them in a variety of unique and powerful ways. Parrying an attack will usually add 5 damage and deflect it, while also fully restoring V1's stamina and health up to the hard damage limit.

The FEEDBACKER is the most common and consistent way to Parry, accomplished by punching at the correct time. It is capable of nearly every form of parry, from reversing melee attacks to deflecting projectiles. The timing for projectiles is a window before the projectile would hit V1, while telegraphed attacks are indicated by a "blip" sound effect accompanied by a yellow spark particle. Some telegraphed attacks cannot be parried, but will still use the indicators to alert the player with the key difference being that the yellow particle is instead blue.

Holding down the melee key will make the KNUCKLEBLASTER create a shockwave that pushes back enemies and deflects projectiles, albeit with less accuracy compared to the Feedbacker. The shockwave deals 1 point of damage to enemies. Directly punching enemies will deal 2.5 damage.

Creating a shockwave with this arm is useful whenever you're in a tight spot. If you're on a platform or near a hazard, you can easily use the shockwave created from your arm to push back enemies or to make them fall, as well as deflecting any projectiles in a radius slightly farther than the parry range.

When jumping off an enemy with the WHIPLASH, the amount of wall jumps and wall cling weight are reset. Use this effect to extend your recovery or retreat when dealing with large encounters.

Pulling a Drone toward you and then hitting it with the Knuckleblaster or the Feedbacker can be a deadly weapon and it awards you with the [+HOMERUN] style bonus. Alternatively, pulling yourself towards a Virtue and killing it with a punch nets you the same bonus.
