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?

“Early Access have allowed us to develop the core features and technology platform of the game of our dreams in the making, which would not have been possible otherwise. We're at a point now where we can finally start to attract the attention of publishers/investors and complete the game; kickstarting this ambitious franchise. You can follow our progress & recommend publishers for us to work with on our Publishers & Investors Info/Status sheet.”

Approximately how long will this game be in Early Access?

“In June 2016 we started looking for a publisher/investor to fund the completion of Interstellar Marines: Aspiration and help us release out of Early Access on Steam and port it onto PS4 and Xbox One consoles. Once we have finalized an investment/publishing agreement, we estimate 17 months from that date until Interstellar Marines: Aspiration is completed. We extremely honored to spend this time with you, the player, and share the experience all the way from pre-alpha to the release.”

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

“Spearhead and Frontliner Editions will only be available in Early Access for those brave enough to support our quest to make the game of our dreams. For the full version we plan on having a Regular and Deluxe Edition. As far as features our plans for the full version include:

  • First Person Simulation
    A razor-sharp focus on creating a truly immersive First Person Simulator via distinct graphics, audio, and gameplay.
  • Tactical Co-op
    The entire game experience designed from the ground up to support up to 4 players in co-op, with true cooperative interaction.
  • Progressive Role-Playing
    Flat and classless progressive character development and skill system that is not dumbed down for consoles.
  • Nonlinear Game Design
    Open and dynamic game world that always presents a multitude of tactical options for navigating the environment.
  • Customizable Arsenal
    A comprehensive selection of weapon models and types, extension upgrades and equipment options, allowing on-the-fly choice in each tactical situation.
  • Thinking AI
    Enemies that react to input from you and the surrounding game world. We would rather have one smart enemy than five stupid ones.
  • Believable Science Fiction
    Realistic and rich sci-fi environments, ranging from claustrophobic space stations to large outdoor worlds.
  • Interactive Storyline
    A cinematic narrative centered around first contact with another sentient species, where your choices and actions will have consequences.

The full version will be more SP/Co-op focused than the current Early Access version where we are implementing and testing new mechanics primarily in a PvP multiplayer environment.”

What is the current state of the Early Access version?

“The game is in pre-alpha and players can expect to experience bugs, missing features, incomplete content, and some game breaking issues. These are the features you can experience right now:

  • Wargames (Sandbox Combat Arena)
  • 2 SP/Co-op Campaign Missions*
  • 4 Difficulty Levels
  • 5 Challenge Missions
  • 9 Multiplayer Maps
  • Dynamic Environment Effects
  • 3 PvP Game Modes
  • 100% Dynamic Lighting
  • Destructible Light Fixtures
  • Full-body Character Simulation
  • Visor Affected by Fog, Dust, and Rain
  • Spectator Mode
  • Movie Mode
  • Playground Mode
  • 3 weapons**
  • Tactical Laser
  • Tactical Flashlight
  • Ragdoll Physics
  • 28 Steam Achievements
  • Dedicated Servers Worldwide
*(Currently available as stand-alone missions)
**(pistol currently uses placeholder model)”

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

“We intend for the price to follow the value of the game. Expect it to gradually rise as we ship new content, but we may need to lower the price on rare occasions to correct for market conditions.”

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

“The community can follow our progress on the Trello Board and vote for features they want to see.”

Update 27 - ITO Test Build 4 Released

We've been hard at work on Update 27 and have made significant progress. This includes tactical reload, a fix for falling through the map in need of testing, and weapon changes for you to provide feedback on.

X-Mayhem Status
Right now there is a bug which spawns the present over and over again in the same space up to millions of times in an attempt to maximize holiday cheer, making the game mode unplayable. One of our programmers is looking at it though, and with his help Santa might be able to save Christmas after all!

Development Status
Several of our volunteer programmers attend university; Understandably, they’re occupied with end of semester projects and studying for finals. Unfortunately, this means development has slowed down and we’re not sure exactly when U27 will be ready.

ITO Player Testing Has Begun For U27

Thank You!

First off we'd like to thank all our friends in the Interstellar Marines community who have given us your support and confidence! We are humbled by the overwhelmingly positive response and are very pleased to announce

ITO Testing!

Our ITO Testing program allows us to post game changes on a beta branch in Steam for ITO players to test, without breaking things for the casual player on the main build. Up until now it's been an exclusive group that requires a signed non-disclosure agreement on file at Zero Point Software to participate but NOT ANYMORE!

We have opened enrollment to anyone who is interested, with no NDA required. Not only is there no NDA, but we encourage our testers to discuss things with other players outside of testing to keep them in the loop.

To become an ITO tester join our Discord Server and post in the roll-requests channel. Then you'll receive access to the testing announcements and the code to unlock the beta branch.

We won't make a public announcement for every iteration of a test build (we could have 10 a day) But we will announce major changes. If you want to follow progress on the game you can also visit our Trello Page we'll be keeping it updated with what we're working on better than we have been previously.

Development Team Update

We've added several new volunteer developers to the team and are VERY excited about our potential new capabilities, some of which have already begun to be realized. We'll be discussing this in more detail once everyone has gotten settled and we see where we're at.

FOR THE LOVE OF THE GAME,

About This Game

Interstellar Marines is an immersive tactical sci-fi First Person Simulator in the making, offering a unique blend of tactical gameplay, dynamic environments and non-scriptet AI. Play Singleplayer or Co-op/PvP on servers around the world.

Interstellar Marines is inspired by movies such as Aliens, Starship Troopers and Saving Private Ryan; and games such as Half-Life, Deus Ex, System Shock 2, and Rainbow Six 3: Raven Shield.

Interstellar Marines is all about evolving the FPS recipe with the inspirations we've assimilated since the birth of the genre. Our goal is an evolutionary leap forward driven by our compulsive interest in science fiction, role-playing, military realism, and respect for first person immersion.

Interstellar Warfare Initiative

It is the dawn of the 22nd century, a time of great hopes and expectations. The discovery of a new and inexhaustible well of power known as Zero Point Energy has revolutionized space travel. Man has escaped the confines of Mother Earth, and gone on to colonize the solar system.


But far away from public awareness an ambitious military project has already taken Man beyond the final frontier, and into the regions of the stars. The powerful Interplanetary Treaty Organization, ITO, is secretly constructing the first human settlement in another star system.

You are a special forces soldier training to join the Interstellar Marines, a part of the secret Interstellar Warfare Initiative being established to protect humanity against potential threats from the confines of the unknown universe.

It's time to evaluate the Interstellar Warfare Initiative and program evaluations are taking place at The Vault, ITO’s most advanced military facility on Earth enclosed deep beneath Groom Lake, Nevada. Supervised by SARA, ITO’s central neural network AI, SARA will program artificial weather and advanced combat training robots to test each warfare initiative to the limits.

This is where the game begins ...

7 Singleplayer/Co-op Missions

Play 5 co-op and single-player missions against unscripted AI with dynamic environment effects or two pivotal missions inside the Interstellar Marines universe, The NeuroGen Incident and Assault on Starcrown Aerospace. Play singleplayer or co-op with up to three friends in intense action with more co-op and singleplayer missions to come!

Wargames (Sandbox Combat Arena)

Unique sandbox combat arena in the making. Wargames is played across 9 distinct interconnected environment zones allowing 64 players to join in the scavenge for combat points, playing alone or in co-op. We have a special Wargames Steam Leaderboard which tracks Combat Points globally, monthly, and survivors of Wargames.

9 Unique Multiplayer Maps Across 3 Game Modes

Take your friends out in Deadlock, Deathmatch, and Team Deathmatch on maps featuring dynamic environment effects such as time of day, rain, thunder and lightning, emergency lighting, fire alarms, moving platforms etc.

Realistic Simulation

With a physics-based dynamic character controller there are no floating hands, and you can even see your feet! The physically present combat helmet has a HUD projected onto the visor and is affected by dust, rain, fogging, and damage. Aim down the sight for the long shots and use the tactical laser to assist aim when hip firing, as there are no artificial crosshairs to break immersion. Use the intuitive crouch and cover system; spacebar (default) peeks over cover, and looking down leans you forward to see over ledges. You can also shoot out the lights and prowl in darkness, or use the tactical flashlight if you’re afraid of the dark.


We hope you enjoy the game, and look forward to developing it with you as we progress through Early Access!

FOR THE LOVE OF THE GAME,
Your team at Zero Point Software
