The ultimate spy-vs-guards simulator. Carefully sneak your way to the objective as Intruders or use the wide variety of tactical gadgets to trap your opponents as Guards. Intruder allows for stealth, teamwork, and environmental interactions never before seen in a multiplayer game.
The game inspires players to approach objectives in a variety of stealthy or aggressive ways. Intruders can carefully sneak through vents, open windows, and swim in bodies of water to reach their targets without detection. Guards, on the other hand, utilize an arsenal of tactical gadgets like motion sensors, remote charges, and security cameras to track down and eliminate the Intruders. The highly interactive environments provide countless paths and approaches to objectives. Players can open windows, crawl through vents, and interact with elevators and other objects to gain strategic advantages.
The game's unique proximity-based voice chat system allows players on both teams to overhear each other's conversations. This leads to intense moments of deception, misdirection, and spontaneous cooperation or conflict. Intruders might eavesdrop on Guards discussing their strategy, then use that information to plan a clever infiltration. Or a lone Intruder might try to bluff their way past Guards by mimicking their communication.
The diverse selection of tactical gadgets encourages creative, emergent gameplay. Players can use motion sensors to detect enemy movement, remote charges to trap hallways, and even comical items like banana peels to trip up opponents. The ability to interact with the environment in meaningful ways is also a key aspect, as players can hack security cameras, open and close windows, and utilize elevators to their advantage.
Coordination and communication are essential, as players must work closely with their teammates to achieve their objectives. Hand signals, radio chatter, and the proximity-based voice chat system facilitate complex strategies and a deep sense of camaraderie.
The game features unique mechanics like the ability to "play dead" and feign being incapacitated, as well as the use of "ragdoll physics" to launch enemies out of windows or interact with their bodies in hilarious ways. The 3D spatial audio system also allows players to pinpoint the location of enemy voices and footsteps, adding to the tense, immersive atmosphere.
