U4GM How to Deal With Arc Raiders Aggression Matchmaking

You jump into Arc Raiders for a few raids, and suddenly it feels like every lobby is out for blood, like the whole map knows exactly where you are and what you are carrying, right down to your stash of ARC Raiders Items. It is not just you. Plenty of players have been saying the same thing in Discords and forums, wondering if they just got rusty or if the chill looters quietly disappeared overnight. Turns out we were not imagining it at all. Embark has now admitted they flipped the switch on a system that actually tracks how you behave in a match, and it is reshaping who you fight against.

What Aggression-Based Matchmaking Actually Does

In a recent conversation, Embark's Patrick Söderlund did not dance around the topic when someone asked why certain players suddenly feel like they are getting dropped into pro-only lobbies. He straight up confirmed that the studio is using aggression-based matchmaking, or ABMM. The idea is pretty simple, even if the code behind it probably is not. If you are the kind of player who pushes every shot, checks every noise, and snaps to PvP the second you spot movement, the game quietly flags you as that type of player. Then it tries to stack you in with others who play the same way, so the lobby ends up full of squads who all want a fight, not just a loot run.

Separating Hunters From Looters

Söderlund also mentioned that this behavior layer sits on top of the usual stuff like solos, duos, and trios. They rolled it out about a week ago, which matches pretty well with when people started complaining that raids suddenly felt different. The whole point, at least on paper, is to protect players who mainly want PvE. If you usually avoid PvP, sneak around, and only pull the trigger when you have no choice, the matchmaking is supposed to put you with others who do the same. It lines up with what Art Director Robert Sammelin hinted at earlier, when he said player behavior was baked into their "complex" matchmaking logic. For anyone new to extraction games, that can be a big deal, because nothing kills early interest faster than getting farmed by stacked veterans every time you spawn.

The Hidden Metrics Behind The Curtain

What Embark is not sharing is the exact checklist that decides who is "aggressive" and who is "defensive", and that is probably intentional. If they said something like "two kills in five minutes makes you aggressive", half the player base would just min max around that line to stay in easier lobbies. Instead, the system likely looks at a bunch of stuff at once, maybe how often you initiate fights, how far you chase players, how quickly you rotate toward gunfire, stuff like that. From the outside it feels a bit mysterious, which can be annoying when your raids suddenly feel way harder, but it also stops everyone from gaming the rules.

Harder Raids As An Unspoken Compliment

The funny thing is, if your matches have turned into nonstop brawls lately, there is a decent chance the game has quietly decided you are one of the dangerous ones and shuffled you toward players with equally sharp aim and nasty loadouts of ARC Raiders weapons. It might feel rough in the short term, especially if you were used to farming weaker squads, but it also means you are on the radar as a real threat, not background noise. For PvE focused players, the hope is that this takes a bit of pressure off and gives them space to learn routes, enemies, and extraction timings without getting stomped every time. For everyone else, welcome to the shark tank.
