But in coop mode, the damage is halved normally like everything else, but the damage cap was calculated twice incorrectly, making it only deal a quarter of 35. There is a glitch for Roundabout EX, the damage it's supposed to deal is exactly 35, or exactly 7 hits for 5 damage each, but because of how it is coded, it only disappears after it exceeds 35 so one more hit is granted.

This glitch has since been removed but is still available on the original patch. The utility of Roundabout and Lobber for staying on screen longer than most shot also help setting a lot on damage on the field before the boss shows up, like shooting both shots upwards while jumping will results in Roundabout coming down later and Lobber bouncing higher on the floor. Charge and Chaser damage is too low, uncharged bullets are very weak because Charge is not meant to be used this way and Chaser is just too weak naturally. Spread and Peashooter fire rate is too fast for proper switching when Lobber and Roundabout both have slower fire rate, Spread also has short range so it is really hard to optimize. The preferred choices is Roundabout and Lobber, they both have more DPS than Peashooter and the EX does better damage when used correctly. Speedrunners use this glitch for almost doubling the damage output.There is a glitch called weapon swap glitch by speedrunners where the cooldown is still counting down after switching weapons, the cooldown isn't set to zero so you are not shooting a new bullet every time you switch, but it isn't paused so when you switch back it can be shot almost immediately again when the cooldown is off, this glitch is patched by pausing the cooldown correctly when switching the weapon.



If you select Expert Mode in the save file with a completed main game, starting a new one stays at Expert Mode.Also, if Cuphead parries a damaging parryable object the same time they touch it, the game will softlock.The game cannot be paused after this soft-lock happens and the only way to get past that is to close the game and reopen it. If Cuphead dies during a boss transition, the boss battle will still continue and the game will soft-lock.6.1 Videos of the listed glitches in action.1.1 Videos of the listed glitches in action.
