One security guard, a pistol, and an entire NYC subway filling up with aliens - this one-person studio project earns its tension through smart chokepoint design, not spectacle.

I have a soft spot for solo-developer games that pick a single idea and squeeze every drop out of it, and Subway Invasion by QH Studios - the work of one developer, Qasim Hussain - is exactly that kind of project. You are not a marine, not a chosen hero. You are a subway security guard who happened to be on shift when things went catastrophically wrong underground, and the game never lets you forget how outmatched you are. That framing matters more than it sounds. Starting with only a pistol and barely enough ammo to get through the first wave, the pressure is immediate and stays constant. The core loop is wave defense layered over resource scarcity. Kill aliens to earn points, spend points on pistol attachments - scopes, flashlights, thermal sights - and eventually unlock sub-weapons like grenades. What gives this more texture than a standard arcade wave shooter is the environmental layer: you can lock doors to funnel enemies through specific corridors, turning the cramped subway platforms and narrow passageways into a puzzle of chokepoints rather than an open shooting gallery. The alien roster adds to this. Some enemies charge straight at you, others divert to attack the train's defenses directly, which means your attention is split and your fortified positions are never truly safe. Later waves bring faster, stronger extraterrestrials that have learned to use weapons, and the difficulty escalation feels deliberate rather than lazy number-pumping. The PS5 version, which preceded this Steam release, was received favorably by critics - a Metacritic score of 88 is nothing to wave away for a solo indie - and early Steam community sentiment has pointed to the ammo-management tension and the spatial control mechanics as the standout qualities. The complete game ships at launch with no gated content, which is worth noting in an era where day-one DLC has become background noise. Where Subway Invasion earns skepticism is in its scope. This is a tightly scoped, singleplayer-only experience on a budget price point, and players expecting a sprawling campaign or multiple environments will need to adjust expectations. The underground atmosphere does a lot of heavy lifting - the claustrophobic corridors suit the genre and give every wave a sense of place - but variety in setting appears limited to the subway system itself. For some players that focused lens will be a virtue; for others it will feel thin after a few sessions. There is also no community around it yet on PC, which means if you hit a wall, you are largely finding your own answers. I keep coming back to the fact that this is one person's game. The intentionality in the ammo system, the alien behavior splitting your focus, the door-locking as active defense rather than set-and-forget - those are choices, not defaults. Small games that know what they are trying to do are genuinely rare, and this one does. Kai, Scout Team

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.
