Inspired by single-player stealth games like Metal Gear Solid, SWAT 3, Splinter Cell, and Deus Ex Intruder takes the concept and transplants it into a revolutionary team-based tactical FPS game. Made by Superboss Games Intruder is a game about players defending (Guards) or infiltrating (Intruders) a high-security facility with only one life each and a limited amount of information the game slows down to a crawl and becomes a high stakes cat and mouse chase, use every gadget, weapon, and information at your disposal to get the edge over your opponent.  

• Tactical Realism: Ragdoll physics, Spatial 3D Voice chat players can only talk to each other if they are near each other or with the use of a hand-held radio but be careful nearby enemies can eavesdrop on you.  Each round you will only get one life once you’re dead it’s over and with only a limited amount of information, you can’t really tell if you’re the only person alive if no one else answers you over the radio.
• Playing around your team is essential if you want to win running and gunning will only get you killed, although useful handheld radios can be dangerous with possible information leaks use hand signals to communicate silently with your team, used by real-life SWAT teams.
• Another character in the game is the Map with the guards having the advantage always with their entrenched position and fortified base of operations with working security cameras, spotlights, and sliding windows but as it is not unassailable intruders can use zip lines, ventilation shafts, and elevators.
• Use a binocular to spot enemy positions use a cardboard cut out as a decoy, a tactically placed banana peel, camera on a stick to peek corners, sticky bombs with motion sensor detonators, riot shields Gadgets are the bread and butter of Intruder use them wisely.
