About Interstellar Marines

Interstellar Marines is a tactical sci-fi first-person game with single-player, co-op and PvP play. You are a special forces soldier training to join the Interstellar Marines, a force being formed to protect humanity from potential threats in the unknown universe. The game combines tactical play, dynamic environments and unscripted AI.

The Interstellar Warfare Initiative

At the dawn of the 22nd century, the discovery of Zero Point Energy, an inexhaustible source of power, revolutionizes space travel. Humanity colonizes the solar system, while the Interplanetary Treaty Organization (ITO) secretly builds the first human settlement in another star system as part of the Interstellar Warfare Initiative.

Your training takes place at The Vault, ITO’s advanced military facility buried beneath Groom Lake, Nevada. SARA, ITO’s central neural network AI, oversees your evaluations, using artificial weather and advanced combat training robots to test the initiative.

Missions and Wargames

The game includes seven single-player and co-op missions. Five pit you against unscripted AI and dynamic environmental effects; the other two, The NeuroGen Incident and Assault on Starcrown Aerospace, take place at pivotal points in the Interstellar Marines universe. You can play alone or co-op with up to three friends.

Wargames is a sandbox combat arena set across nine distinct, interconnected environment zones. Up to 64 players scavenge for combat points, alone or in co-op. A leaderboard tracks combat points globally and monthly, as well as Wargames survivors.

Multiplayer modes

Nine maps support three modes: Deadlock, Deathmatch and Team Deathmatch. Their dynamic environmental effects include changes in time of day, rain, thunder and lightning, emergency lighting, fire alarms and moving platforms. You can play PvP on servers around the world.

Tactical simulation

A physics-based character controller gives your character a visible body, including feet, rather than floating hands. Your combat helmet has a HUD projected onto its visor, which can be affected by dust, rain, fogging and damage. You aim down sights for long shots, or use a tactical laser to assist with hip firing; there are no artificial crosshairs.

The crouch and cover system lets you peek over cover and lean forward to see over ledges. You can shoot out lights and move through darkness, or use a tactical flashlight.
