Not a persistent MMO
- Kill Strain is a session-based multiplayer shooter or action game — matches are short, instanced rounds, not a persistent shared world.
- It's catalogued here as "Online action game" — a related but distinct genre from the persistent-world MMOs this site otherwise covers.
- It's included in this directory because it's commonly searched for by people trying to figure out whether it counts as an MMO — this page exists to give you a straight answer.
Real MMOs to check out
- This entry is intentionally excluded from MMOFinder's platform, genre, and catalog-wide statistics, since it isn't a persistent-world MMO.
- PlanetSide 2 is the closest thing to a genuinely persistent-world MMO shooter if that combination is what you're after.
- If you came here specifically to check whether this game is an MMO: it isn't, by the definition this site uses (a persistent, shared, many-player online world) — but it may still be worth playing on its own terms.
