Social deduction dressed up in first-person 3D sounds promising until you check the concurrent player count and realize finding a lobby is the actual challenge.

I went looking for something to scratch the hidden-role itch outside the usual suspects, and Killer: Infected One of Us landed on my radar. First impression: the premise is solid enough. Four to ten players drop into an Arctic research station set in 2040, split between Healthy survivors and one or more Infected players running a silent infection campaign. The Healthy side has to figure out who is carrying Virus-40, administer an antidote to cure the right person, and keep the station operational through a series of maintenance quests. The catch is brutal and interesting on paper: if you inject a healthy teammate by mistake, the antidote kills them instead. That one mechanic adds genuine tension to the accusation phase, which is handled through anonymous voting backed by voice and text chat. The first-person perspective is the hook that separates this from the top-down social deduction crowd. Moving through the station corridors yourself, watching body language through player movement, checking who lingers near a terminal too long - it could be compelling. And honestly, in a full lobby of ten people who are all communicating, there are flashes of something worthwhile. The anonymous vote system keeps paranoia high, the bonus system rewards both good deduction and successful deception, and the secret locations scattered around the map add a layer of investigation that the genre often skips. Here is the problem, and it is not a small one. The concurrent player count sits at roughly two at any given moment. That number is not a typo. The community forums have threads asking if the game is dead, and those threads go unanswered. Getting a natural lobby together without organising your own group beforehand is close to impossible right now. The game was originally titled Killer Among Us 3D before a name change prior to launch, and that rushed-to-market energy never fully left the product. Polish is thin, the English text still has rough edges, and there is no ranked structure or progression system to keep a dedicated base coming back. For the specific shooter-adjacent audience reading this: do not come here for gunplay. There are no weapons, no TTK to analyse, no movement tech worth discussing. It is a first-person social deduction game that borrows the camera angle from shooters but shares almost nothing else with the genre. If you are the type who organises Discord game nights with eight friends and wants something weird and cheap to fill a slot, there is a functional game buried here. Play it with a full pre-made group on voice chat and the anonymous voting and misfire-antidote mechanics do generate genuine moments. Alone or with randoms via matchmaking, you will be staring at an empty lobby screen. Fred, Scout Team

GamerScout Verdict

Only worth it if you have 7-9 friends ready to queue together - solo matchmaking is effectively broken by an empty playerbase.

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.
