Two different unlocks
Playing can unlock weapon variants. Buying a Robux pass is a separate listing. A New Weapon Earned notification is the checkpoint for a variant. A pass price is not that checkpoint.
- Use the gear already in your session.
- Watch for New Weapon Earned.
- Press Unlock on that notification when it is offered.
- Check Weapons. Rewards is a separate top-right menu in the 5 November recording.
Crystal Kraken and Bug are names that appeared on those notifications. They do not publish a timer, a kill count, or a mutation recipe.
What the 5 November hotbar showed
Pistol, Bow, Great Sword, Baseball Bat, Throwing Knives, Push, Repulse, Move, and Team Designator. That is an observed bar, not the whole catalog. The developer also describes shooting, slicing, biting, injecting, and powers inspired by fictional characters, without listing every name.
With the Pistol selected, click fires and E near a subject hands it over. A later narrated session also hands over a Great Sword and identifies E for that handover. That does not prove every weapon can be given to a subject, or that the subject will always attack. Ragdolls can fight each other, according to the developer.
A kill loop that walkthroughs actually show
One beginner video uses the shotgun on a map whose captions come out as Bolab, Biolab, or Bio Lab. Ragdolls there stand close together.
- Equip the shotgun and get the group in range.
- Turn Doctor mode off before the farming loop.
- Eliminate the prepared subjects.
- Use Reset Experiment so the subjects return.
- Confirm they are back before you fire again.
The same video says to use that map for kills, then switch maps when you want a different experiment. It does not publish how many kills the next weapon needs. Another walkthrough's mastery screen uses the Railgun as an example at 1,200 kills. Follow the number on your current weapon panel. The 1,200 figure is a dated example, and Update 4 announces a weapon unlock and progression rework for 14 November 2026.
There is also an off-sale game pass named Railgun, with no price and a blank description. Do not treat that pass and the mastery example as the same offer.
Other names from walkthroughs
Grenades are described as needing an unlock first. Leaf Blower Minigun, Taser, Shrink Ray, Large Ray, and a Squish power are named in gameplay guides. The developer separately says you can apply heavy weight and watch ragdolls squish. No damage, rarity, or ammo rules were published for these names. Push, Repulse, and Move are force or placement tools on the observed hotbar. Team Designator is a tool, not a damage weapon.
How to choose
Use the Pistol when you need either a shot or a subject that is holding a gun. Use the shotgun loop when the goal is repeated kills and the subjects are already grouped. Use a melee weapon when the test is contact. Use Push, Repulse, Move, or Hands when the test is position rather than a kill. Then read Doctor if the question is what the body did.
Cards for the named gear and the current passes are in Weapons and passes.
