What Is Anybrain? Arc Raiders' Anti-Cheat Partner

What Anybrain is

Anybrain is Embark Studios' external partner for machine-learning-based cheat detection. They provide behavioral analysis services to Arc Raiders (and other game publishers in their portfolio). Per Embark's May 7, 2026 "Ensuring Fair Play" dev blog, Anybrain is Layer 2 of Arc Raiders' four-layer anti-cheat stack — sitting alongside EAC (Layer 1), Abnormal Match Compensation (Layer 3), and the new kernel-level AC in testing (Layer 4).

What Anybrain actually detects

Anybrain's models ingest a high-frequency feed of player input data: mouse-movement curves (the angular-velocity distribution as you flick to a target), aim-velocity deltas (the change in mouse-velocity rate between sample points), click-cadence patterns (how rhythmic your firing inputs are), headshot-rate distributions (your accuracy distribution across engagement types and weapons), engagement-timing fingerprints (the timing between visible-target appearance and your reaction). The models flag patterns consistent with aimbot, triggerbot, no-recoil scripts, and other input-augmenting cheats.

Why Anybrain is fundamentally different from EAC

EAC's kernel signature scanner is inside-out — it looks for cheat code in the game process memory, kernel memory, and loaded drivers. The detection signal is "is there cheat code present?" Anybrain is outside-in — it looks at player input behavior from the server side. The detection signal is "do your inputs look like a cheater's inputs?" This matters because Anybrain doesn't care what your cheat looks like in memory or whether it injected into the process. A perfectly hidden cheat that produces aimbot-like inputs still gets caught by behavioral ML.

The Anybrain humanizer defense

The defense against Anybrain is not better signature hiding — it is making your inputs look like a human player's inputs. Humanized aim curves (smoothness 200-400 range, not 0-100) that match real-player angular-velocity distributions. Randomized per-engagement reaction timing (±15-30ms) so the timing between visible-target appearance and your response varies naturally. Capped statistical outputs — headshot rate dialed back from theoretical max so your accuracy distribution stays within the legitimate-player range. Per-shot jitter on recoil compensation curves so the inverse-recoil pattern doesn't read as machine-perfect. This is engineering work that requires writing your own cheat code, not reselling community scripts.

What does NOT work against Anybrain

Static smoothness curves (max smoothness 0 = clear aimbot signature). Static reaction-timing curves (consistent timing = inhuman). Max FOV cone settings (snapping to targets outside human peripheral vision = anomalous). 100% headshot rate (no human achieves 100% across engagement types). Static recoil compensation curves (pixel-perfect inverse recoil = obvious script). The cheap-cheat-vendor pattern of "max everything" is exactly what Anybrain catches inside a few sessions.

The Flippy parallel (different game, same lesson)

The March 13, 2026 Overwatch ban wave banned 18,159 accounts, including streamer Flippy who had no cheat history. The community's leading theory: HyperX NGENUITY and Corsair iCUE RGB peripheral driver smoothing produced behavioral patterns that flagged Defense Matrix's ML. Even legitimate driver software can trip behavioral thresholds. The implication for Anybrain users: your humanizer settings must be tight enough that your inputs are below the threshold that flags RGB-driver smoothing on legit players. Conservative defaults survive; aggressive tuning gets caught.

The Anybrain advantage for Embark

For Embark Studios, Anybrain represents a meaningful engineering advantage over publishers building behavioral ML in-house. Anybrain has been refining their models across multiple games and years, accumulating training data and detection methodology that a single publisher's anti-cheat team can't easily replicate. The partnership lets Embark focus on game development while outsourcing the ML expertise. Other publishers (notably Krafton with PUBG's ~39,000 AI-video-review bans through Nov 2025) have built behavioral ML internally; Embark chose external partnership.

What "Anybrain-aware" cheat engineering looks like

A cheat tuned for Anybrain ships conservative defaults from day 1: smoothness 200+, randomized reaction timing, capped headshot rate, visible-only filtering enabled, conservative FOV cones (10-25° typical). The cheat does not maximize aim performance — it deliberately leaves performance on the table to keep statistical outputs in the legitimate-player range. Most cheap cheat brands skip this because conservative defaults look less impressive on a feature list. The ones who survived Arc Raiders' January 2026 and post-February-pivot ban waves shipped Anybrain-aware tuning from launch.

What changes when Layer 4 deploys

Embark's May 7, 2026 announcement of a new kernel-level AC in active testing alongside EAC adds another detection vector. Anybrain doesn't go away — it stays as the behavioral layer. The new kernel AC adds signature/kernel-memory scanning that EAC currently handles plus whatever proprietary detection logic the new vendor brings. A cheat that handles EAC + Anybrain humanization gets the longest detection window through Q2 2026, but when Layer 4 deploys (timeline unconfirmed, expected by end of Q3 2026), additional tuning will be required. Active engineering vendors will pivot; reseller storefronts will lag.
