Embark Studios has finally addressed one of the most persistent questions surrounding its upcoming title: how does aggression-based matchmaking actually work? In a detailed new blog post, the developers are attempting to demystify the "invisible social machinations" that govern player encounters in Topside, specifically addressing fears regarding player reputation and lobby types.

Debunking Myths About Arc Raiders' Aggression-Based Matchmaking

There has been significant community speculation about whether a single kill could flag a player as hostile or if certain lobbies are strictly PvE. Embark has moved to clarify that the system is far more nuanced than a simple binary of "friendly" versus "hostile."

To understand how the matchmaking functions, it is important to look at the core principles the developers have established:

  • The Playstyle Scale: Matchmaking isn't based on two separate buckets. Instead, players exist on a continuous spectrum of aggression.
  • Pattern Recognition: The system looks for long-term behavioral patterns rather than reacting to isolated incidents or single kills.
  • Engagement Focus: Matchmaking prioritizes how you engage with other Raiders, not necessarily what you do after a fight ends.

According to the developers, while some players are bloodthirsty and others are purely cooperative, most fall into a middle ground of being "opportunistic" or "cautious." The system attempts to place you near your position on this scale without making every match entirely predictable.

Refined Behavioral Judgments

Embark has recently implemented two significant changes to how the game tracks player behavior to ensure more accurate matchmaking:

  1. Defending yourself is no longer a hostile action: Previously, the system struggled to distinguish between someone starting a fight and someone merely reacting to an attack. Now, defending yourself is treated differently than initiating combat, preventing cautious players from being mislabeled as aggressive.
  2. Reduced weight for low-activity rounds: Rounds where little interaction occurs—such as those spent spawning or surrendering—now carry less weight in your playstyle history to ensure the data reflects genuine gameplay choices.

Common Misconceptions Clarified

To prevent player superstition, Embark provided a list of specific "myths" that have been circulating in the community. They confirmed that several factors players think influence their matches actually have no impact on the aggression-based matchmaking algorithm:

  • Loadouts: Your gear and kit cost do not scale lobby difficulty.
  • End-of-round surveys: While feedback is used for design, it does not act as a "lever" to change your next match.
  • Looting: Taking gear from knocked-out players does not impact your matchmaking profile.
  • Squad Leaders: The leader of a squad does not carry more weight; every member influences the collective squad profile equally.
  • Crossplay: Turning crossplay on or off changes the player pool and queue times, but it does not change the "tone" of the matches.

While these clarifications aim to provide peace of mind, some players remain skeptical. Even with the developer's reassurance that a single kill won't ruin your experience, the unpredictable nature of Topside means that "spicy" lobbies can still appear seemingly out of nowhere. However, by shifting the focus toward long-term patterns and distinguishing between aggression and self-defense, Embark is working to ensure the ecosystem feels fair for all types of Raiders.
