How We Rank Anomalies
This tier list evaluates Anomaly performance in typical public lobbies, not guard loadouts or pro scrims. We weigh kill pressure, ability reliability, map synergy on Backrooms-style layouts, learning curve, and how coordinated guard teams punish mistakes.
Tiers are snapshot opinions for the current icce build. Horror asymmetry games shift quickly — a hotfix that adds blink immunity to a guard tool can drop an S-tier pick to B overnight. Read the disclaimers below before treating any row as permanent meta law.
S tier anomalies win rounds without perfect play. A tier anomalies dominate when you understand matchups. B and C tiers can still clutch with map knowledge or disorganized lobbies. D tier would mark anomalies that struggle even with skill and RNG favor — none of the eight current picks sit that low, though SCP-999 comes closest as a non-lethal outlier.
S Tier — Round-Winning Threats
S-tier anomalies force guards to change default strategies the moment the role reveal plays. They combine reliable downs, strong mobility or zone control, and punishment tools that scale into late round when survivors clump for safety.
- The Boiled One (S) — Burst pursuit monster. Excels at collapsing isolated guards and converting one down into chain pressure. Hard difficulty but rewards map reads; weakest when guards hold long sightlines with stun tools ready.
- The Locust (S) — Swarm and area denial. Shines in choke-heavy wings where spread fire cannot clear every angle. Hard to play in open atriums but terrifying when guards stack in a single room.
- SCP-682 (S) — Tank rampage profile. Absorbs focus fire better than glass-cannon picks and wins extended fights. Medium mechanical demand makes it a common S-tier recommendation for players who dislike blink timing games.
A Tier — Skill-Expressive Predators
A-tier anomalies win most lobbies once you learn ability cadence and guard habits. They fall off when teams communicate callouts, pre-aim corners, or run counters specific to your kit.
- Ao Oni (A) — Sustained chase pressure. Medium difficulty with straightforward melee loops. Strong on maps with long hall runs; weaker against stagger chains and early barricades.
- SCP-173 (A) — Blink punish assassin. Hard because line-of-sight rules demand discipline. Unstoppable in solo-queue chaos; coordinated teams that never break eye contact limit your ceiling.
- GUILT (A) — Psychological debuff specialist. Hard kit that erodes guard confidence and spacing. Payoff is enormous in low-coordination lobbies; falls to disciplined squads that stick together and call debuff timers.
B and C Tier — Situational Picks
Lower tiers are not throw picks — they trade raw kill speed for utility, setup time, or non-lethal disruption that still advances anomaly win conditions in niche scenarios.
- Smile Room (B) — Ambush and zone control. Medium difficulty with trap-like territory denial. Devastating when guards wander alone; struggles against sweep groups that clear rooms methodically.
- SCP-999 (C) — Support and distraction. Easy to pilot but lowest direct kill pressure. Can still swing rounds by splitting guard attention or enabling other anomalies in future modes; currently the weakest solo carry.
D Tier — Currently Empty
We leave D tier open rather than force a punching-bag label. None of the eight roster anomalies are unplayable in public matchmaking. SCP-999 sits at C because friendly disruption is real but slow — not because the character is D-tier useless.
If icce adds joke anomalies or heavily nerfed variants, D tier will host them explicitly. Revisit this section after balance patches on our Updates wiki.
Guard Counterplay Snapshot
Tiers assume average guard aim and mixed loadouts. Heavy defensive stacks — extra tools gamepass, coordinated flashlights, door holds — compress S-tier advantage by one letter grade in practice.
Anomaly selection RNG means you cannot always pick S tier. Learning B-tier zone control on Smile Room often beats misplayed Boiled One dashes. For guard-side responses, read How to Beat Anomalies and the per-anomaly pages linked from our Anomalies hub.
