RaiderRep definitive guide
ARC Raiders Reputation System
A complete guide to the ARC Raiders karma system, Aggression Based Matchmaking (ABM), official Embark playstyle-based matchmaking, Speranza database reputation checks, reputation tiers, Hero to Bandit scoring thresholds, and how to fix negative karma before your next drop.
Aggression Based Matchmaking (ABM) mechanics
Aggression Based Matchmaking (ABM) is the community name many players use for Embark's official playstyle-based matchmaking. In May 2026, Embark published how the system works in Notes on The Matchmaking System. That in-game playstyle profile is separate from RaiderRep's community Trust Score.
What Embark officially tracks
Embark forms lobbies around two goals: fairness (for example, matching equal squad sizes where possible) and enjoyment (matching players with similar playstyles). Your playstyle across previous rounds — especially how you engage with other Raiders — sits on a continuous scale, not a friendly-versus-aggressive switch. Some Raiders are almost always cooperative; some are highly PvP-focused; most land somewhere in between.
How playstyle matchmaking behaves
- Similarity is more likely, not guaranteed. You have a higher chance of meeting Raiders with a similar past playstyle and a lower chance of meeting very different ones — but there is no hard guarantee every round.
- Behavior shapes future lobbies gradually. If you change how you play, the kinds of Raiders you tend to meet shift over time. Your history influences what is most likely — it never locks you into one experience.
Topside stays unpredictable by design. Embark is not trying to segregate playstyles entirely — danger and surprise encounters remain part of the game.
Confirmed RaiderRep scoring (community ledger)
RaiderRep starts every Embark ID at 100 and adjusts standing with structured incident reports and verified vouches. That community ledger is transparent and auditable — it does not read or mirror Embark's hidden in-game playstyle profile.
Official matchmaking myths (Embark, May 2026)
Embark cleared up common community theories in their May 2026 matchmaking article. These apply to in-game playstyle matchmaking — not RaiderRep Trust Score.
- There are not only two kinds of lobbies — friendly and aggressive. Playstyle is a continuous scale, and most Raiders fall somewhere between the extremes.
- One shot or kill does not immediately put you in PvP-focused lobbies. Matchmaking looks at patterns over time, and changes are gradual rather than instant.
- There are no PvE-only lobbies or servers where other Raiders will never attack you. Topside always carries risk.
- End-of-round survey feedback does not affect matchmaking. Embark uses it for trends and design decisions, not as a next-lobby lever.
- Your loadout does not affect matchmaking. Kit cost and gear are not used to scale lobby difficulty.
- Patches and updates do not reset your matchmaking profile. You may see slightly rougher matches right after an update while the player pool is small, but it recovers quickly.
- Looting knocked-out players does not affect matchmaking. The system focuses on how you engage with other Raiders, not what you do with their gear afterward.
- Matchmaking is not based only on the squad leader. Each squad member influences the squad profile equally.
- Turning crossplay on or off changes who is in the matchmaking pool (and matchmaking time), but it does not guarantee the tone of your encounters.
Speranza database reputation check
A Speranza database reputation check is the practical pre-raid habit: scan a raider before you trade, share loot, or squad up. Search an Embark ID on RaiderRep to see report history, vouches, Trust Score, and whether the player looks like a Hero, neutral operative, or Bandit.
The 3-second camera scanning workflow
The fastest workflow is simple: ask for the Embark ID, run the lookup, inspect the score and recent incidents, then decide whether to continue the interaction. The goal is not to punish strangers; it is to avoid preventable scams, betrayals, and toxic squads.
ARC Raiders karma system and reputation tiers
The ARC Raiders karma system is best understood as a behavior ledger. Positive actions like revives, honest trades, and friendly squad play build standing. Toxic conduct, loot theft, betrayal, exploiting, scam trades, and cheating push a profile toward Hostile or Bandit status.
Self-defense versus instigating aggression
Embark matchmaking (May 2026): defending yourself is no longer treated the same as starting a fight. Previously, cautious Raiders could be scored as more PvP-focused than they actually were; Embark now weights initiation and self-defense differently. Rounds with little Topside interaction — such as spawning and surrendering — also carry less weight in your playstyle history.
RaiderRep community reports: self-defense is still context. A report should explain whether a player defended themselves or initiated the encounter through fake friendliness, squad betrayal, harassment, or scam behavior. Evidence links help separate survival from predatory play.
Hero to Bandit scoring thresholds
RaiderRep score math is intentionally public: Trust Score = 100 + all report points + (vouches x 2). The incident table below shows how reports affect standing.
Hero+15
Dominated the raid and led the squad to victory. Exceptional play, leadership, or sacrifice that turned the tide.
Medic (Reviver)+20
Revived teammates under fire, sacrificed position or loot to get a teammate back up. True squad player.
Friendly Raider+10
Solid teammate. Shared loot, communicated well, played the objective, and didn't leave you behind.
Funny Raider+5
Made the raid entertaining. Great vibes, hilarious moments, and memorable interactions that made the session.
Good Trader+5
Completed a marketplace trade honestly. Communicated clearly, delivered as promised, no games.
Toxic-10
Verbal abuse, harassment, racial slurs, or intentional griefing (blocking doors, making noise to attract AI).
Loot Theft-15
Snatching loot from a kill they did not participate in, stealing quest items, or emptying chests while you fight.
Betrayal-20
The ultimate sin. Pretended to be friendly (via VOIP/Emotes) or joined a squad, then killed teammates for loot.
Exploiter-30
Abusing map glitches, getting under the map, or using game-breaking bugs to gain an unfair advantage.
Scammer Trader-50
Agreed to a marketplace trade, then scammed or ghosted — did not deliver items as promised.
Cheater-50
Use of external software (Aimbot, ESP, Wallhacks, Speedhacks). Report these to Embark Studios as well.
How to fix negative karma
To fix negative karma, build a stronger positive record. Revive teammates, finish honest marketplace trades, communicate before fights, share critical loot, and avoid repeat reports. RaiderRep does not wipe history on a timer, so recovery comes from consistent positive standing rather than waiting out a hidden reset.
Recovery checklist
- Earn Hero, Medic, Friendly Raider, and Good Trader reports.
- Use evidence links when disputing a report or explaining context.
- Stop the repeat behavior that created the negative karma.
- Ask squadmates and trade partners to vouch only after real positive interactions.
ARC Raiders reputation system FAQ
How does the ARC Raiders reputation system calculate aggression?
Embark uses playstyle-based matchmaking: your behavior across previous rounds — especially how you engage with other Raiders — helps estimate where you sit on a continuous cooperation-to-PvP scale. Similar playstyles are more likely to match, but never guaranteed, and shifts happen gradually over time. That in-game profile is separate from RaiderRep, which calculates community Trust Score from a permanent ledger: every report has a fixed point value, every verified vouch adds +2, and the score starts at 100.
How does the 3-second camera scanning reputation check work?
Players often describe the Speranza database scanner as a quick camera or lookup check before trusting another raider. On RaiderRep, the practical version is an Embark ID search: enter the ID, scan the report history, and review the score before trading or teaming.
What are the seven behavior tiers from Hero to Bandit?
The seven guide tiers are Hero, Helpful, Trusted, Neutral, Doubtful, Hostile, and Bandit. They summarize RaiderRep score ranges from high positive standing to nefarious negative karma so players can understand risk quickly. These are community Trust Score bands, not official Embark matchmaking buckets.
Does defending yourself hurt reputation differently than instigating?
In Embark matchmaking, defending yourself is no longer treated the same as starting a fight — a live change Embark confirmed in May 2026. Low-activity rounds such as spawning and surrendering also carry less weight in your playstyle history. On RaiderRep, reports remain context-based: describe whether a player defended themselves or initiated betrayal, scams, or harassment, and use evidence links so other players can evaluate the difference.
Does one betrayal instantly put me in hostile lobbies?
No. Embark matchmaking does not overreact to single moments. One shot, kill, or betrayal does not instantly move you into PvP-focused lobbies; the system looks at patterns over time and changes tend to be gradual.
Does my loadout affect matchmaking?
No. Embark confirmed that matchmaking is not driven by your kit and that lobby difficulty is not scaled based on how much your loadout costs.
Does end-of-round feedback change my next lobby?
No. Embark uses end-of-round survey feedback to study trends and inform design decisions, but it is not used as a lever for your next lobby assignment.
How do you fix negative karma in ARC Raiders?
For Embark playstyle matchmaking, changing how you play gradually shifts the kinds of Raiders you are most likely to meet — but there is no guarantee and no PvE-only escape from risk. For RaiderRep community standing, recover by earning positive reports: revive teammates, complete honest trades, share loot, communicate clearly, and avoid repeat toxic or betrayal incidents. RaiderRep has no time decay, so recovery requires fresh positive history to outweigh old negative reports.
