Dossier Summary
Skill loadout
8 AbilitiesEvery skill MUL-T can equip, with the slot it occupies, its cooldown and its proc coefficient. Skills listed as alternates replace the default for that slot and are unlocked through the challenges underneath.
| Skill | Slot | Cooldown | Proc | Availability |
|---|---|---|---|---|
| Auto-NailgunFires nails in a wide, haphazard corkscrew. Releasing the trigger starts a pause of just over a second before nails can be fired again. | Primary | — | 0.6 | Default |
| Rebar PuncherA slow, heavy single shot with 1.8 seconds between shots. Retool can be used to skip the cooldown and fire again. | Primary | — | 1.0 | Alternate |
| Scrap LauncherFires rockets at 100 m/s that explode in a radius, with sweet-spot damage at the centre. A full cycle of shots and reload takes about 2.4 seconds. | Primary | 1.5s | 1.0 | Alternate |
| Power-SawA continuous saw that ticks ten times per second at base attack speed and pulls you slightly toward whatever it hits. | Primary | — | 1.0 | Alternate |
| Blast CanisterLobs a canister on a 6-second cooldown. Holding the key displays the projectile arc and blast radius. | Secondary | 6s | Canister: 1<br>Bomblets: 0.3 | Default |
| Transport ModeGrants armour and a speed boost, then forces a forward charge at full speed. Ramming a large enemy ends the charge early but deals four times the damage and stuns it. | Utility | 6s | Charge: 1.0<br>Ram: 1.0 | Default |
| RetoolSwaps between your two primaries in 0.4 seconds. Carrying two primaries and being able to swap them belongs to this skill rather than to a passive. | Special | 0.5s | — | Default |
| Power ModeSwitches to a power-oriented mode. Documented mechanics note that its movement effect runs through the slow coefficient instead of being a direct speed increase. | Special | 5s | — | Alternate |
The proc coefficient scales how strongly on-hit item effects trigger from that skill's damage. Reported by players — Compiled from player reports and community guides; confirm in your own run.

Reading the loadout
MUL-T carries 8 skills across 4 slots (Primary ×4, Secondary, Utility, Special ×2). 4 of them are alternates rather than a default pick, which puts a real choice in the Primary, Special slots.
- Cooldown range
- Shortest is 0.5s on Retool; longest is 6s on Blast Canister. That spread sets how often the kit can answer a problem rather than absorb one.
- Proc profile
- Highest proc coefficient is 1.0 on Rebar Puncher, Scrap Launcher, Power-Saw. The primary sits at 0.6.
- Unlock work
- 3 challenges are tied to this survivor, listed underneath. Clearing them is what opens the alternates rather than the character itself.
The kit splits into 5 slots built around dealing damage and 3 slots built around repositioning or burst windows. The primary's proc coefficient of 0.6 means it triggers on-hit item effects less reliably than a full-strength hit, so builds leaning on proc items will want another source.
This breakdown is computed from the table above rather than quoted from a guide, so it moves automatically whenever a listed value changes.
Origin and version history
- MUL-T has been on the roster since the base game, which puts the character inside the balance pass that patch 1.21 was written for.
- Hallowed Concepts also shipped a skin for MUL-T, so the most recent cosmetic change and any mechanical change to this character came from the same release.
Origin and patch attribution are taken from the store listings and the developer's own announcement for patch 1.21.
