A Reddit user going by m0rpheus23 just dropped something that sits firmly at the intersection of two passionate but niche communities: achievement hunters and Linux gamers. The tool is called Sentinel, and as PC Gamer reports, it adds a fully functional achievement system to games played outside of Steam on Linux.
What Sentinel actually does
The concept is straightforward. After downloading Sentinel from GitHub, you point it at either the Steam Web API or an external source like SteamHunters. The tool pulls achievement data from whichever source you choose, then monitors your save files in real-time, cross-referencing progress against that data. When you hit the trigger condition, the achievement fires.
A GIF shared on the project’s GitHub shows it working live in Middle-earth: Shadow of Mordor, with an achievement unlocking the moment an arrow hits a fire pit. That is not a delayed sync or a manual check. That is real-time detection doing exactly what it promises.
The key here is that Sentinel was built specifically for games downloaded outside of Steam. If you are running titles through Heroic Launcher (which handles your Epic Games Store library on Linux), Sentinel tracks those too. You get on-screen notifications, multi-step achievement tracking, global completion percentages when using the Steam API, and even custom notification sounds if the default ping does not do it for you.
info
Sentinel requires achievement data to exist somewhere online to work. Games with no Steam presence and no external achievement database will not be supported, but the pool of applicable titles is large given how many games have Steam achievement data.
The achievement hunting community is bigger than you think
This might look like a tool for a tiny audience, but achievement hunters are a surprisingly dedicated group. RetroAchievements, a platform that adds achievement support to classic retro games, has been running for 14 years and now covers over 10,000 games with nearly 600,000…
