Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

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.”

Update 1192 + Mapping Contest


Hello agents and welcome to update version 1192!

We received a lot of feedback stating people wanted some more hardcore server settings to make competitive play more viable. Our first step along that way is introducing limited spectating mode in this update. This server room option will only allow you to spectate your own teammates once you've died to deter ghosting and other such nonsense.

The full change log is below:

New Additions


  • Limited spectator mode for more hardcore gameplay and ghosting deterrent!
  • Limits spectating to only your teammates and turns off player cards
  • This will be turned on by default in all SeriousPlay rooms
  • To use it in your own rooms just check the "Limit Spectating" box when creating a room

  • Server room filters!
  • Filter rooms by name, mode, map, empty, full, locked, etc.
  • Filter by name, mode, or map just needs to contain the input. So filtering by "side" for instance would give you all rooms playing Riverside, Cliffside, Mountainside, because those map names contain "side".

Changes
  • Votekick changed to need more than half the room to vote to kick a person
  • Optimized some network traffic code
  • Can no longer hear full volume voices when joining a room and before picking a team
  • Added timer to Riverside B1 Raid rooms

Fixes
  • Fixed Riverside B1 raid rooms not loading B1 raid mode correctly when joining
  • Fixed issue where Guards would have 6+ CS grenades on certain maps
  • Fixed faulty server room filtering for Japan rooms
  • Attempted fix for incorrect reflective damage message
  • Multiple small bug fixes and optimizations


White Box Mapping Contest

Starting now and ending May 1st is the White Box Mapping Contest!

The goal of this mapping contest is to have map makers focus on gameplay and map design over graphics, materials, etc. In the official maps, the design process involved fast prototypes, playtested until the gameplay felt just right before any graphical additions. The original versions of our beloved Riverside consisted of only Unity cubes in fact. Buildings in Intruder are designed to be realistic and functional, while also good for the guarding and infiltration gameplay. We want mappers to go through this same process. To accomplish this we've established the following rules:

  • 80m x 80m x 20m size limit for the playable area
  • Focus on the gameplay over the graphics and details
  • For main building geometry, you can only use 2 materials we provide: grey for floors and white for walls/ceiling
  • Props may have textures, bushes and trees should be textured for visual concealment
  • Avoid using Unity terrain if possible (lumpy terrain will probably be disqualified)
  • Ensure optimization and bake most lighting, marks will be off for poor performance
  • Map submissions end May 1st

Maps will be judged on the following:

  • Obeys the rules and fits in the size limit
  • Promotes Intruder-y plan and pick your infiltration route gameplay (Not too open and not too linear)
  • Buildings have realistic, functional layouts, but does not hamper gameplay
  • Performance
  • Map maker playtests and gives progress pics of their map design
  • It's fun!

We will have a Developer's pick winner as well as a Player's Choice winner.

Again, for more information and how to start mapping, join the Discord (https://discord.gg/superbossgames) and respond to this post: https://steamcommunity.com/app/518150/discussions/0/1846946102858525072/

Anyway, hope these updates are welcome additions. Let us know what you want to see in the next one!

p.s. we might be looking for video editors if that's your thing.

Update 1169 + Roadmap preview


Hello agents and welcome to our first patch/update: Build 1169! And you can play it now!

Before we get down to the specifics, we want to say thank you to everyone and that the launch has been amazing! We even managed to get to the Steam front page as a best seller, so thank you all!

With that we got a lot of immediate feedback. There were definitely a lot options and settings customizations that people wanted so we made sure to get those in with this first patch. This includes gameplay settings like hold to lean or hold to aim-down-sights instead of toggle only, various graphics settings, and mic boosting. You also have volume sliders for every player in-game as well. Check them out in "New Additions."

At the end of this article we will also write a preview for the roadmap and what's to come for the game. Steam launch was a big milestone for us but it's really only the beginning.

New Additions
  • Binoculars will now send photos and sender name to teammates even if they don't have binoculars. Great for silent communication and info sharing.

  • Unified server list now has an "All" region which shows all rooms on all regions at once
  • Microphone volume boosting added to options menu
  • Volume sliders added to each player, so you can turn them down if their mic is too loud
  • Mouse inverted toggle added to options menu
  • Toggle VSync option added to options menu
  • Frame rate limit slider added to options menu (only works when VSync is off)
  • New "Gameplay" section added to options menu
  • Toggle or hold Lean options added
  • Toggle or hold Aim-down-sights options added

Changes
  • Shotgun pickup now says "You found a non-lethal Shotgun"
  • Vote kick cool down changed to 5 minutes
  • Tool tips updated to reflect current settings for ADS
  • Tutorial updated to suggest default ADS controls
  • Put message on Superboss logo page that Intruder is a work in progress
  • Reflective damage for all kinds of attacks (including headshot) turned down to 10 instead of taking the full damage of the attack
  • Official rooms will be set to have All-round Reflective damage on so new players will experience fewer TKs
  • Energy recovery speed at < 15 sped up a little bit
  • Sweet new main menu background

Map Maker
  • Shotgun pickups and shotgun ammo pickups added to Map Maker
  • Shotgun added to EquipmentManager

Fixes
  • Riverside Server Room plaque visible again
  • Removed ping limit kicking in offline mode (Tutorial/Map Maker testing)
  • You will auto un-lean when respawning
  • Stuck vote kick menu if person leaves fixed
  • Fix for empty spaces in Team menu and player info panels with wrong info
  • Simplified and reworked team switching code should eliminate some other problems
  • Fixed early round TKs not registering in rooms without reflective damage on
  • Fixed poor deforming remote charges when they touch window frames

Also, we have begun separating out rooms into more types such as Serious Play - Microphone Required, Casual, and Beginners rooms. Please adhere to the rules of the rooms or feel free to make your own. Remember that rooms you create are hosted on our dedicated servers, so there is no difference in speed to official rooms.


The roadmap is something a lot of people have been asking for. This is just a small preview of things we will be doing and some things we want to do. We will have a separate post as well going into more detail about the Roadmap and the future of the game.

Coming Soon
  • A new version of the website with much improved and detailed player profiles, roadmap, and other cool features:

  • Quality of life improvements and more user settings
  • Better server/room filtering
  • Various graphical improvements and cleanups of official maps (including Oceanside)
  • More map maker tools for your custom maps
  • Options to limit spectating to just teammates for competitive matches

Bigger Stuff
  • Move Map Maker over to Steam Workshop
  • Redone HUD and Menus
  • Redone Inventory System
  • Physics enhanced animation system
  • New Map: Codename Facility
  • New Map: Codename City Skyscrapers
  • More weapons and gadgets (some map/mission specific)
  • More mission types/game modes

Even bigger
  • AI/bots
  • Dedicated servers that can be run by players as well (Current rooms are hosted on our dedicated severs)
  • More player and weapon customization
  • Stats and progression system hooked up in-game and website
  • Clan and competitive game support
  • Fleshed out lore and maps of the island Intruder takes place on

This is just a preview of what's to come, but expect a larger Roadmap post detailing some of these out and showing examples of what we have on them already.

Please drop by the Discord any time at https://superbossgames.com/chat to hang out with Devs and the community. New clans and competitive matches are starting to form there as well (more on that later).

Again, thank you all so much for the support and we hope you are enjoying Intruder.

About This Game

Intruder is the stealth multiplayer experience. We were inspired by the great single-player campaigns of Metal Gear Solid, SWAT 3, Deus Ex, and Splinter Cell, and aim to bring that gameplay into a team-based multiplayer shooter. Intruder allows for stealth, teamwork, tactics and environmental interactions never before seen in a multiplayer game. 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 emergent gameplay come from the players’ actions to provide an experience you will never forget.

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 Unity3d level editor plugin to create your own Intruder maps and game modes
  • Regular updates and new features based on community feedback!
