SCP retroBreach Tier List Hub

Why tier lists matter in SCP retroBreach

SCP retroBreach is an asymmetrical Roblox FPS from Sandbox Engine. Every round mixes Class-D, Foundation staff, MTF and Security, Chaos Insurgency, and playable SCPs fighting through LCZ, HCZ, and EZ toward Gate B and surface exits. A clean tier list does not replace map knowledge—it tells you which tools and anomalies punish mistakes fastest when the facility collapses.

Use this hub to jump into two focused rankings: the SCP tier list for anomaly power and the weapons tier list for guns like Saiga-12, FAMAS, HK416, XM8, AKM, AKS-74U, Makarov, and Desert Eagle. Pair rankings with keycards and the broader items catalog so your upgrades through SCP-914 actually stick.

How we rank for this meta

Tiers here weigh round impact, not lore prestige. An SCP that deletes squads in HCZ corridors ranks above one that needs perfect setups. A shotgun that clears Class-D riots ranks above a sidearm that only shines in Council Rescue. We also factor counters: MTF SCRAM and NVG pressure against SCP-096 and SCP-966, GOC and Serpent’s Hand spawn waves, and how TIX cosmetics never change combat (skins stay cosmetic).

S tier — Changes the round if the player is competent.
A tier — Strong defaults; forgives mid play.
B tier — Situational winners with clear weaknesses.
C tier — Starter or fallback tools you replace when better loot appears.

Balance shifts with Sandbox Engine patches. Christmas-era gun additions and SCP-106 / SCP-457 tweaks already moved pocket-dimension and burn rules. Re-check after major updates, then re-read sibling pages instead of trusting outdated lobby talk.

SCP rankings at a glance

Playable anomalies are the horror half of the FPS. SCP-106 and SCP-096 usually lead for mobility and punish windows. SCP-173 and SCP-049 reward team coordination and hallway control. SCP-457 and SCP-966 stay dangerous but meet harder hard-counters once Security and MTF bring optics and fire discipline. Full reasoning, matchups, and escape-route notes live on the SCP tier list.

If you main Foundation or Chaos Insurgency, study which SCPs you should never peek alone in HCZ and which ones you can kite toward Gate B while teammates push LCZ checkpoints.

Weapon rankings at a glance

Human factions win with ammo economy, magazine depth, and zone control. Newer additions—Saiga-12, FAMAS, HK416, XM8, AKM, AKS-74U, and Makarov—sit beside classics like Desert Eagle in spawn tables, loadouts, and SCP-914 Fine / 1:1 / Coarse chains. Primaries decide LCZ armory fights; pistols finish wounded runners in EZ. See the full breakdown on the weapons tier list and the practical pickup guide under weapons.

How to use these lists in a live round

1. Spawn, identify your faction goal (escape, recontain, rescue O5, extract Class-D).
2. Check your starting gun against the weapons tiers—swap at the first armory if you are stuck with a C-tier sidearm.
3. Upgrade keycards early so HCZ and Gate B routes open before decontamination timers punish late LCZ looters.
4. If SCPs are free, avoid staring contests with SCP-096 and never turn your back on SCP-173.
5. Spend TIX only on cosmetics; power comes from positioning and loadout, not the shop.

Cross-check faction playstyles in the Factions Hub so your tier pick matches your job. A top-tier shotgun on a lone Class-D still loses to coordinated MTF if you never reach Chaos Insurgency extraction.
