X-Ray Visor

X-Ray Visor is a passive trait ability belonging to the Thief Runner Shell in Marathon. It provides persistent wall-penetrating vision that highlights both enemies and loot containers through environmental geometry, giving the Thief a constant stream of positional and item information without needing to activate any ability. This passive awareness means the Thief always knows where nearby loot is located and where threats are positioned relative to walls and cover.

X-Ray Visor is especially powerful in the Thief's looting-focused playstyle because it removes the need to physically enter rooms to check for valuable items, allowing the Thief to prioritize high-value targets immediately and skip empty areas entirely. The ability to see enemies through walls also serves a defensive function: the Thief can pre-plan grapple escape routes knowing where opponents are, and avoid ambushes that would catch other Runners off guard. The additional note that X-Ray Visor can hack enemy optics adds an offensive dimension to the trait, though the precise mechanics of that interaction require further verification.
