Intruder is a team-based multiplayer shooter played in rounds as either an Intruder or a Guard. Intruders try to complete objectives such as stealing a briefcase or hacking terminals; Guards defend those objectives. Either side can also win by eliminating the opposing team.
Players use weapons and gadgets to scout, distract, deceive, or trap opponents. Guards can monitor security cameras and set motion sensors near explosives, while hand radios and silent hand signals help teammates coordinate. Proximity voice chat can also give away a player's position to nearby enemies.
Interactive environments support climbing, swimming, and crawling through vents, alongside features such as sliding windows and elevators. Physics can create tactical opportunities, including pretending to be dead, and rounds can be played on official or player-created maps.
Players who enjoy Intruder often praise its tense, tactical stealth, creative gadgets, and proximity chat, which can turn coordination and even casual conversation into part of the match. Many describe it as especially entertaining with friends, with physics-driven mishaps adding a comic side to the standoffs. At the same time, reviews frequently report trouble finding populated lobbies; some also mention the challenge of facing experienced players or wanting more content.
