X-Ray Multiplayer Extension Mod is a free-to-play game utility from the xrMPE team. This simple mod allows you to play S.T.A.L.K.E.R.: Call of Pripyat with your friends in a fully multiplayer experience. Instead of the traditional player vs. player (PvP) experience offered by the base game, it creates a cooperative player vs. environment (PvE) experience.

However, it’s important to note that X-Ray Multiplayer Extension Mod is a standalone mod that doesn’t cover the original game. Instead, it is its own campaign. Be sure to check out the Anomaly Mod or the Dark Signal Mod.

Survive hordes of mutants

X-Ray Multiplayer Extension Mod still feels loyal to its Call of Pripyat roots, despite being a standalone game not set in the main continuity. The design and the premise still feel like something that would happen in the same universe. In this game, you can join friends in a section of the Chernobyl Exclusive Zone. Your objective is simple: survive the waves of mutants, one after the other.

The rest of the mod simply lifts off assets from the base game: character models, weapons, and game mechanics. It makes it intuitive to existing players, although it doesn’t add a new feel to the game. An exciting aspect of the game is that it includes artifacts, although it changes the effects. For example, the Ray of Hope now scares mutants away.

Still, one of its strengths is the surprisingly stable multiplayer support—something challenging to pull off. It also offers a comprehensive guide to help players join or create their own games with the mod. It even supports the creation and importation of custom maps. With the latest updates, the mod has grown to include various game mods beyond its original defense mode.

Enjoy S.T.A.L.K.E.R. with friends

Instead of fighting with friends, X-Ray Multiplayer Extension Mod lets you play cooperatively with friends or strangers in the online lobby. By making a standalone that can be played separately or as an add-on to Call of Pripyat. It largely retains the feel and function of the original game, but it introduces a couple of its own modifications. Overall, its setup makes the game exciting while keeping its intuitive feel.
