How to Read This Stat Sheet
This wiki page is the central stat sheet table for every playable Anomaly in Be an Anomaly or Guard on Roblox. Developer icce ships eight entities drawn from creepypasta, SCP-inspired designs, and original horror kits. Each row below summarizes community tier placement, combat role, and pilot difficulty — the same fields shown on our individual anomaly profile pages.
Numbers here describe observable behavior in public lobbies on the Backrooms map, not datamined server constants. Cooldown bands, effective health, and mobility notes come from repeated testing and patch verification on the Updates hub. When icce hotfixes an ability, we amend this table within days.
Guards use the counter section before spending credits. Anomaly mains use role tags to decide practice priority. Cross-link to the Tier List for meta snapshots and to Wiki Overview for round flow context.
- Tier — S/A/B/C community ranking for round impact
- Role — what the kit does in a standard match
- Difficulty — how punishing mistakes feel for the pilot
- Slug — profile URL under /anomalies/{slug}/

S-Tier Stat Notes: Boiled One, Locust, SCP-682
The Boiled One (S · Burst / Pursuit · Hard) closes distance after guard mispositions. Pursuit tools chain off isolated rotates in maintenance wings. Effective health is moderate — burst windows matter more than sustained trades. Guards counter with buddy stacks, stun utilities at choke frames, and no solo peeks into yellow hall T-junctions.
The Locust (S · Swarm / Area Denial · Hard) dominates open generator rooms and long corridors where cover is thin. Swarm abilities force early utility burns from guard teams. Spread formation beats clumping; stagger flashlights so one sweep cannot clear every angle. Mobility is high in open space, lower in tight stair cores.
SCP-682 (S · Tank / Rampage · Medium) trades instant burst for sustained rampage presence. Absorbs focus fire better than glass picks; wins extended objective fights when guards dump all damage into one target. Kite during rampage cooldowns and save heavy weapons for finale compression zones.
A-Tier Stat Notes: Ao Oni, SCP-173, GUILT
Ao Oni (A · Chase / Pressure · Medium) is the baseline chase threat with readable ability loops. Medium difficulty rewards map knowledge over frame-perfect inputs. Strong on long hall runs; weak against stagger chains and early barricades. Chip damage accumulates — guards should rotate before health hits critical.
SCP-173 (A · Blink Punish / Assassin · Hard) enforces line-of-sight rules both ways. Hard rating reflects dual skill checks: guards must blink-check; pilots must bait breaks without overcommitting. Never solo-hold a door while 173 is unaccounted for. Coordinated teams compress this pick to B-tier effectiveness.
GUILT (A · Psychological / Debuff · Hard) layers debuffs that amplify panic in voice comms. Wins come from spacing erosion, not raw DPS. Clear callouts and regroup timers beat rushing revives after debuff ticks. Guard teams with calm shot-calling negate much of the kit's ceiling.
B-Tier and C-Tier: Smile Room & SCP-999
Smile Room (B · Ambush / Zone Control · Medium) controls map pockets through ambush timing rather than open chases. Zone denial wins rounds when objectives force static holds in smile-adjacent wings. Guards slice pie corners and listen for audio cues; B-tier is not a free win for guards.
SCP-999 (C · Support / Distraction · Easy) is the roster support pick with the lowest direct kill pressure. Easy pilot difficulty — abilities favor distraction and morale swings. Anomaly players enable teammates by drawing attention; guards avoid wasting heavy cooldowns on 999 if higher-tier threats remain active.
Selection, Gamepasses, and Practice Routes
Anomaly selection is random each round unless you own the 2X Anomaly Chance gamepass (250 R$ per Rolimon's listings). That pass doubles odds — it does not change stat values in this table. Use guard rounds to study spawn angles for every row above.
Progression gamepasses like 2X Damage Gain (150 R$) affect guard-side scaling, not anomaly base kits. 2X Credits and 2X XP (349 R$ each) accelerate shop unlocks between rounds on the Backrooms map.
Queue focused practice with friends: ten rounds on one anomaly teaches more than fifty random queues. After patches documented on Updates, re-read tier rows before ranked-style public grinding.
