A scrappy, years-in-development tactical sci-fi shooter with co-op and PvP, still technically in Early Access after more than a decade.

Interstellar Marines is a first-person tactical shooter set in a sci-fi military universe, developed by the small independent studio Zero Point Software. The pitch is ambitious: dynamic environments, non-scripted AI, and a blend of single-player, co-op, and PvP modes that aim for something between a mil-sim and a cinematic action game. On paper, it sounds like exactly the kind of scrappy indie project worth rooting for. In practice, the reality is considerably messier. The game launched into Early Access in 2013 and, as of the most recent updates, remains incomplete. That is not a typo. Over a decade of Early Access development has produced a product that still lacks the full content roster originally promised. What is here includes a handful of maps, combat scenarios against AI enemies, and multiplayer modes on community servers. The AI does show occasional flashes of the non-scripted behavior the developers advertised, reacting to sound and flanking with more intent than a typical corridor shooter enemy. The atmosphere is genuinely tense in the right lighting, and the sound design does real work making the marines feel grounded and weighty. The problems are hard to ignore, though. The mixed Steam review score (sitting around 53 percent positive from nearly eight thousand reviews) tells a story of a fanbase that believed in the concept and slowly ran out of patience. Content is thin for the amount of time the game has been available. The RPG and simulation genre tags feel optimistic given what is currently playable. There is no meaningful character progression system, no branching story, no build variety to speak of. For someone coming in expecting RPG depth, there is essentially none. The tactical shooter side is functional but sparse. Who is this actually for in its current state? Honestly, a narrow slice of players: people who appreciate unpolished atmospheric shooters, enjoy co-op sessions in low-stakes environments, or have a specific nostalgic attachment to the project from its early crowdfunding days. If you are hunting for a deep tactical sim or any kind of RPG experience, this does not deliver on either front. The Early Access tag at this point is less a promise and more a warning. If Zero Point Software ever ships a full 1.0 release with the AI systems, story content, and progression mechanics they originally described, the conversation changes. Until then, what you are buying is a very long work-in-progress with a small but committed community, some genuinely eerie corridor environments, and a lot of unrealized potential sitting in a development backlog.

Skip unless you are a die-hard tactical sci-fi fan willing to accept a decade-old Early Access game that may never fully ship.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
