"These machines are my finest scouts and agents, reborn in a form that gives them Sight unrivaled."
The Twins are Hardmode bosses that can be fought anywhere on the surface at night.
While in Revengeance and Death Mode, the Twins are fought in phase 2 simultaneously, and get a third phase in which their attack patterns become more complex.
Spawn
The Twins can be summoned manually using a Mechanical Eye at night. They also have a 10% chance to spawn randomly at dusk once a Demon or Crimson Altar has been destroyed, as long as they have not been defeated in the current world. Their arrival is announced by the status message: "This is going to be a terrible night...".

Behavior
In Expert Mode
- Both Twins move at a higher velocity and acceleration.
- Retinazer fires lasers faster in Phase 1, which have higher velocity, but more inaccuracy and lasers get faster as health lowers.
- Retinazer charges more often at a faster velocity and performs 1 more charge.
- Spazmatism fires cursed fireballs faster in Phase 1, which have higher velocity and fireballs get faster as health lowers and its flamethrower attack is faster in Phase 2.
- Spazmatism charges more often at a faster velocity and performs 2 less charges.
In Revengeance Mode
The Twins will become enraged when fought during the day, becoming more aggressive, charging further and firing projectiles more often. Their projectiles also have increased velocity when enraged. Spazmatism's flamethrower will also have a longer range.
Phase 1
- Retinazer alternates between staying diagonally above the player and firing bursts of 3 purple lasers and performing 3 longer but slower charges towards the player.
- Spazmatism alternates between moving horizontal with the player and quickly firing cursed fireballs and performing 8 quicker but shorter charges towards the player.
Phase 2
- The Twins enter Phase 2 at 70% health. If one of the Twins is in Phase 1 while the other is in Phase 2, that twin in Phase 2 will take negligible damage. If the player has reversed gravity, both twins will immediately transition to Phase 2.
- Retinazer continuously fires red lasers at the player, with the pattern of hovering above the player and slowly firing 3 shots followed by hovering to the side of the player and firing a quick burst of 8 shots.
- Retinazer fires lasers faster and more frequently if the player has reversed gravity.
- Spazmatism alternates between slowly chasing the player while breathing shadowflame and cursed flames and performing 4 long and fast charges towards the player.
Phase 3
- The Twins enter Phase 3 at 25% health, or the other twin has been defeated.
- Retinazer performs a new attack by performing 2 long charges after firing lasers and firing several homing missiles during the first charge.
- Spazmatism performs a new attack by hovering beneath the player and firing semi-homing shadowflame and cursed fireballs, uses its flamethrower attack for less time, charges longer and faster, and moves faster while breathing shadowflame fireballs.
- Both Twins have increased velocity and acceleration and Retinazer's homing missiles have higher velocity and acceleration while enraged.
- If Retinazer has been defeated first, Spazmatism stops breathing shadowflame fireballs and performs a longer set of charge attacks, with 4 charges while the final charge travels further. When charging, contact damage is increased by 10%.
- If Spazmatism has been defeated first, Retinazer fires lasers much more quickly and performs 4 charges, firing homing missiles during the first and last charge.
In Death Mode
- Both Twins' speed and acceleration increases, and their attack delay reduces as health lowers.
- Retinazer fires lasers from farther away in Phase 1, decelerates faster and has a shorter delay before charges as health lowers, performs 1 more charge, and homing missiles move and accelerate faster and home in on the player sooner.
- Spazmatism decelerates faster and has a shorter delay between charges as health lowers, and fires cursed fireballs while charging in Phase 3, with the addition of shadowflame fireballs after Retinazer has been defeated.
In Master Mode
- The Twins enter Phase 2 at 60% health.
- Both Twins have increased speed.
- Both Twins cycle through attacks faster in Phase 1.
- Both Twins can fire projectiles while at a closer distance to the player and have more accurate shots.
- Both Twins charge more frequently in Phase 1 and charge up to 6 times.
- Retinazer fires spreads of lasers while transitioning to Phase 2.
- Retinazer has increased speed and faster phases during Phase 2.
- Spazmatism fires spreads of cursed fireballs while transitioning to Phase 2.
- Spazmatism catches up to the player more quickly while performing its flamethrower attack and said flamethrower attack is faster and more accurate.
In Revengeance Master Mode
- The Twins enter Phase 2 at 85% health and Phase 3 at 40%.
- Both of The Twins' speed and projectile phase durations are decreased during Phase 1.
- Phase 1 charges last longer and are more frequent.
- Both Twins have a random amount of charges in Phase 2.
- Retinazer fires spreads of lasers and missiles while transitioning to Phase 2.
- Spazmatism fires spreads of cursed and shadowflame fireballs while transitioning to Phase 2.
- Spazmatism catches up to the player more quickly while performing its flamethrower attack.
- Spazmatism breathes both cursed flames and shadowflames.
In Death Master Mode
- Phase 1 charges last shorter but are even more frequent.
During the Boss Rush
Aftermath
- If the Early Hardmode Progression Rework option is enabled, new ores will be generated in the Underground and Cavern layers:
- If The Twins are the first mechanical bosses to be defeated, Mythril and Orichalcum Ore will be generated.
- If The Twins are the second mechanical bosses to be defeated, Adamantite and Titanium Ore will be generated.
- If The Twins are the third mechanical bosses to be defeated, Hallowed Ore will be generated in the Underground Hallow biome.
- If The Destroyer and Skeletron Prime have also been defeated:
- The Bandit will begin selling the Momentum Capacitor.
- The Drunk Princess will begin selling Vodka, Screwdriver and White Wine.
- The Archmage will begin selling the Arctic Bear Paw, Frosty Flare, Cryophobia and Cryogenic Staff.
Tips
- For more elaborate strategies on defeating The Twins, including weapon and arena recommendations, see Guide:The Twins strategies.
- Be sure to damage The Twins at a somewhat equal rate prior to phase 2, to make sure that neither become invulnerable.
- Try not to have both Twins in phase 3 at the same time, as they will become much more difficult to dodge.
- While it is easier to leave Retinazer alone towards the end of the fight, it is very difficult to do so due to its lower health. More often than not, the player will end up with both Twins in phase 3.
- Be aware of Retinazer's firing patterns in phase 2, it will shoot 3 lasers at a low firing rate followed by a fast burst. The player should time their movement so they have enough wing time to avoid the burst by flying diagonally up and away from The Twins to keep them safe from Spazmatism.
Trivia
- Retinazer and Spazmatism's formal designations, according to Draedon, are HSx-00 and HSy-01, respectively.
