SCP: Secret Laboratory is a free multiplayer horror game set inside a Foundation site during a full containment breach. Each round assigns your role at random: Class-D trying to escape, a Scientist waiting on rescue, a Facility Guard, or one of the anomalies hunting everybody else. Death is permanent for that round, and the facility runs on hard timers that will kill you whether or not anything else does.
Your choice of equipment defines your damage output and playstyle. This guide ranks every major option, explains what makes each one strong, and tells you which builds they pair best with.
Equipment Rankings
| Equipment | Tier | Best For | Notes |
|---|---|---|---|
| COM-15 | S | Class-D and Scientists who need something rather than nothing. | A slow firing 9x19mm sidearm from PG Arms with high damage per shot. |
| FSP-9 | A | Guards holding short corridors in Light and Heavy Containment. | The standard issue submachine gun of Facility Guards: light damage per hit, high rate of fire, and a magazine that empties quickly if you panic. |
| Crossvec | A | Anyone who picks one up in Heavy Containment and wants accuracy at short range. | A compact automatic weapon sitting between the FSP-9 and the rifles, controllable enough to land headshots in a corridor fight without a rifle's weight. |
| MTF-E11-SR | B | Trading with SCPs at range while three teammates fire at the same target. | The Nine-Tailed Fox rifle and the strongest general purpose firearm in the game, which is why an organised respawn wave usually flips the direction of a round. |
| Logicer | B | Chaos Insurgency pushing Entrance Zone or holding the Surface for escaping Class-D. | The Chaos Insurgency light machine gun, carrying enough ammunition to keep firing through the window where everyone else has to reload. |
S-Tier: COM-15
A slow firing 9x19mm sidearm from PG Arms with high damage per shot. It is a backup rather than a primary, and it is common enough that Class-D often find one first.

Equipment Progression Path
The order you should acquire equipment as you progress:
- Starting gear → Enough to clear Light Containment Zone
- FSP-9 → Your first real upgrade, available early
- Crossvec → Mid-game upgrade with good scaling
- COM-15 → Best-in-slot, aim for this by late game
- Upgrade to max → The power spike from max upgrades is enormous
Equipment Tips
- Always upgrade your primary equipment before diversifying. One strong option beats three mediocre ones.
- Match your equipment to your build's stat priorities for maximum scaling.
- Decontamination begins at 11 minutes 45 seconds, earlier than the fifteen minute figure players quote. Start your own clock at round start and be out of Light Containment with a full minute in hand.
- Check our tier list for how equipment rankings affect overall build effectiveness.
