Among Us did it first, did it better, and still has a player base. Killer Inside Us is the budget shadow of that game, and the lobbies to prove it.

I checked the concurrent player count before writing this, and it sat at zero. That is the most honest thing I can tell you about Killer Inside Us going into 2025. Released in late 2020 by Source Byte, this is a 3D third-person social deduction game built on the same bones as Among Us: four to ten players split between crewmates and impostors in a space station, where the killers murder and sabotage while the crew either votes them out or fills a task bar to win. The concept works on paper. The execution is the problem. The core loop is functional, just barely. As an impostor, you kill crewmates when they are isolated, trigger sabotages to create chaos, and try to stay off the vote. As a crewmate, you complete tasks to push the progress bar while watching your back. There is a 3D perspective here instead of the flat top-down view of Among Us, which sounds like an upgrade but in practice mostly means the camera angle adds friction to reading the map. The social deduction side, which is supposed to be the whole point of a game like this, is thin. There is no proximity chat system, no visibility-cone mechanic, no emergent tech that rewards experienced players. You talk in text, you vote, someone gets ejected. The loop is shallow in a genre where depth is the entire value proposition. The player population problem is not a minor caveat, it is the product. Community forum posts from players describe being unable to find a single lobby when searching. Peak concurrent player records hover around one person. Cross-platform multiplayer is technically supported across PC, Mac, and Linux, which means nothing if none of those platforms have people online. This is a game that requires at minimum four players to function. If you do not have three to nine friends who already own it and are willing to coordinate a session, this is effectively a solo install that does nothing. Even if you manage to get a full lobby together, reported bugs include dead players being able to contribute to the task bar progress, which breaks the crewmate win condition entirely. From a performance standpoint, system requirements are almost comically light: 2 GHz processor, 1 GB of memory, DX10 graphics. It will run on anything. That is not a compliment. It reflects the scope of the project. There is a cosmetic DLC in the form of an animal hat pack, which says everything about where the development priorities sat. The handful of Steam reviews that exist are net positive, mostly from players who bought it with friends in a bundle, which is the only context where it makes any sense at all. The honest answer to whether you should buy this is: only if you are assembling your own lobby of people who do not already own Among Us or Goose Goose Duck, and you are hunting for the cheapest possible entry point into the social deduction genre. As a pick-up-and-play game where you queue into strangers, it is dead. As a party night option for a group that wants to spend as little as possible on a throwaway session, it technically works. But the moment someone in your group opens Among Us on their phone for free, the argument for Killer Inside Us evaporates completely. Fred, Scout Team

GamerScout Verdict

Only worth it if you are assembling your own private lobby and need the cheapest possible social deduction entry point - queue into randoms and you will find nobody.

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.
