What the developers have to say:

Why Early Access?

“Intruder is a fully-playable 5v5 multiplayer game... but we ain’t done yet! Intruder’s loyal alpha-testers have been playing the game and the most-requested feature is bringing the game to Steam. Here it is!

Launching a multiplayer game on Steam is a big job and we’re a small team. Early Access will help us make sure we do it right! Your purchase of Intruder during Early Access helps fund continued development of Intruder, and gives you a voice during development.”

Approximately how long will this game be in Early Access?

“We anticipate that Intruder will be in early access for 12-24 months.”

How is the full version planned to differ from the Early Access version?

“We want to add…
  • Graphics updates
  • More weapons
  • More gadgets
  • More missions
  • More official maps
  • More mod tools
We’re curious about...
  • Costumes and customization
  • AI controlled opponents
  • Deep lore
We want to hear from new player and old fans what features they most want and use that feedback to drive development.”

What is the current state of the Early Access version?

“Intruder is a already a fully-playable multiplayer game with lots of features:
  • Five-versus-five gameplay: guards vs. spies
  • There are currently 4 weapons and 12+ gadgets in the game.
  • Four official levels in the game with tons of player-created levels (many of which we think are rad).
  • Map creation tools and a friendly community of modders.
  • Custom missions / gamemodes can be created for each map.
  • Stat tracking connected to your Steam profile.
There's a ton of game here, and we're just getting started.”

Will the game be priced differently during and after Early Access?

“We will increase the price of the game as we complete new features and eventually leave Early Access.”

How are you planning on involving the Community in your development process?

“We've always developed Intruder with deep involvement from our community of alpha players. Intruder has an extremely active Discord with players, map-makers, and community-run tournaments. We're coming to Steam to invite an even larger group of players to join us in making Intruder be the best possible stealth multiplayer game ever.”

“There is a pivot point in most tactical multiplayer games, a moment where plans crumble and everything goes wrong, and--if everyone is friendly-- it makes the game ten times better. Swat 4 had it. Rainbow Six had it. And Intruder has it. Hell, Intruder quantifies it.”
Rock, Paper, Shotgun

“Factor in full friendly fire and you'll see that Superboss Games have created something rare – a shooter where you really have to think before pulling the trigger.”
PC Gamer

“Intruder is tense. It might be the scariest first person shooter I’ve ever played. It’s a game about learning fieldcraft, a certain way of doing things. That’s why I think it’s one of the best multiplayer shooters I’ve played.”

About This Game

Intruder is a stealth multiplayer experience, inspired by the great single-player campaigns of Metal Gear Solid, SWAT 3, Deus Ex, and Splinter Cell. The goal is to bring aspects of these games into the gameplay of Intruder, and turn it into a team-based multiplayer shooter. Intruder allows for stealth, teamwork, tactics, and environmental interactions never seen before in a multiplayer game.

Team-Based Stealth Multiplayer
  • Lure enemies into motion detectors near explosive traps.
  • Watch enemy movement through live security cameras and alert your teammates using the hand radio.
  • Use real SWAT hand signals to communicate silently when enemies are nearby.
In Intruder, amazing stories and immersive gameplay come from the players’ actions to provide an experience you will never forget.

Immersive FPS Simulation
Experience an immersive FPS simulation in Intruder with gameplay mechanics of climbing the environment, crawling through vents, and swimming through the waters. Last but not least, experience realistic ballistics with windage and bullet drop in effect.

3D Audio
Communicate with your teammates using both the hand radio and proximity voice chat. But be careful, your enemies can also hear you speak if they are near! However, you can also use this to your advantage to deceive the enemy.

Key Features
  • Team-based stealth multiplayer: Guards vs. Intruders.
  • Immersive FPS: climb, crouch, crawl, and swim through the environment.
  • Use gadgets to trick, trap, distract and outsmart your opponents.
  • Eavesdrop on the opposing team with spatial 3d voice chat.
  • Use “ragdoll physics” to launch your foes out of windows, or to play dead while the enemy walks right past you.
  • Truly interactive buildings with working security cameras, spotlights, sliding windows, ventilation shafts, and elevators.
  • Stealth-based missions with multiple objectives and escape routes.
  • Powerful Unity 3D level editor plugin to create your own Intruder maps and game modes.
  • Regular updates and new features based on community feedback!
