BreakDoor Weapons, Poison, and Laboratory Research

Doors and turrets buy time. Weapons and laboratory research spend that time on a counterpunch. BreakDoor’s official listing promises six legendary weapons ending with Horn of Counterattack, described as powerful enough to slay even the final-form Demon. That line is the Human late-game pitch. This page is how the laboratory actually fits a numbered room, which research lines are worth a look, and why a Horn in a converted room is just a story you tell in the lobby.

You still need printers and an entrance. Read the economy guide and door upgrades if those are not already a habit. Role timing sits on How to Play Survivor. The turret that covers you while you research sits on room turrets.

Six legendaries, one named finish

The listing is the source for the six-weapon claim and for Horn of Counterattack as the closer. This wiki does not invent the four middle names or a damage table we cannot read on a live UI. Open the laboratory in your room. Progress the weapon line when the door is stable. Treat Horn as a timing problem, not a spawn toy. If Hunters have already evolved and rescue is close, climbing the weapon line beats a seventh factory. If it is minute four and wood is still wood, the Horn is a rumor.

Powerhouse is ten million damage as a Human. That badge is a long fight, not a reason to skip cash machines. Deal damage after you have a room that still exists. A hallway hero with starter tools feeding two Demons is not on the Horn plan.

The laboratory is personal

Research and bonuses belong to you, not to a shared team stash. Your neighbor’s Lethal Poison does not cover your entrance. Your Life Wizard portals do not teleport their gold into your pocket. Play the lab like a private tech tree that dies if the door pops. That is why this page keeps nagging about occupancy. Home Sweet Home is the first research: be in the room.

Lethal Poison is the research that changes Hunter identity math. It can convert original Hunters and ties to No Second Chances. That is a different prize than a convert you created from a Human (From Prey to Predator). Original versus converted matters for Hunter Slayer on the other side, and it should matter to you because an original Demon who survives poison is still a wipe machine. Research poison when you can actually finish it, not as a panic click while the warning state is unanswered.

Human research lines track Cutting Edge. Class stages track Breakthrough. Life Wizard is a 25,000 Gem class whose portal work includes Twin Portal. Magnetic Storm Warrior is 30,000 Gems. Those Gem sinks are account unlocks; redeem codes first, then buy a class, then still pay round cash to use the lab. Mechanist-era Mech damage tracks Iron Awakening. If an event banner says Mechanist, this is the combat research to look at, not a reason to abandon the door.

What to research on a live clock

Minute one: nothing. Printers and wood. Mid-round quiet: weapon line plus a Human research tap if the turret is already covering the entrance. Mid-round loud: door. Once an original Hunter is snowballing Evolution, Lethal Poison becomes more interesting than another factory. Last four minutes: Horn of Counterattack if you are on that ladder, Mech damage if Mechanist is the active combat plan, portals if you are Life Wizard and still have a room to return to.

Do not research in the hall. Do not research as a convert unless you have decided you are now a Hunter, in which case this page is the wrong manual (How to Play Hunter). Do not assume Map-wide miracles from a lab you never opened. Open it. Read the rows. Spend on the row that answers the Demon who is actually at the glass.

Horn of Counterattack is a clock, not a personality

The Horn’s official job is killing a final-form Demon. Final form implies you failed to end the hunt early, which is normal, because two Hunters evolve as the night runs. The Horn is the Human answer to that official warning. It is also a trap for people who starve doors to rush a name. A final-form Demon at an open entrance does not care what the weapon is called. Climb the six-legendary line behind a real panel and a turret that is already firing. Then take the fight in a room you still own.

If you never see the Horn in a given night, you did not necessarily play wrong. Twenty minutes is short. Printers, door, turret, then weapons is a legal order. Badge hunters can chase Powerhouse, Cutting Edge, Twin Portal, Iron Awakening, and Breakthrough across many rounds. One round should chase rescue.

Use the Guides Hub when you are unsure which system starved the lab. Use the Players Hub for role identity. Use the tier list when you want community rankings of kits. Use Updates when Mechanist or a new research row ships. Use Getting Started if you are reading this before you have occupied a numbered room.

A clean weapons night is almost rude in how late it starts. You printed. You lifted wood. You bought automatic fire. You opened the laboratory only when the entrance could survive a glance away. You spent on poison when an original Hunter was the problem, on Mech when Mechanist was the problem, on portals when you needed to be two places without donating a convert. You treated Horn of Counterattack as the last legendary, not the first shopping click. Then you either dropped a final-form Demon or you lived long enough for rescue without ever needing the speech. That is the laboratory used as a tool. The other version is a highlight name on a room that already belongs to the other team.
