Steam Achievement Manager

Steam Achievement Manager (SAM) is a free, open-source Windows application for viewing and managing achievements and compatible statistics in Steam games. It can unlock or relock supported achievements, inspect their state, and edit certain statistics exposed through a game’s Steamworks configuration. It is a focused achievement utility - not a game launcher, guide, card farmer, or optimizer.

SAM Picker is the game-selection component of Steam Achievement Manager. After you extract SAM, SAM.Picker.exe opens your available game library so you can choose a title; each game opens in its own achievement management window. You can also enter a Steam App ID when a game does not appear in the automatic list.

Yes - SAM can act as a Steam achievement unlocker for games that allow their achievement state to be changed through the local Steam client. But calling it only an unlocker is incomplete: it can also relock achievements, show their state, inspect unlock times, and edit compatible statistics. Availability depends on how each game implements achievements.

Yes. SAM is free to download and use, with no paid edition, premium tier, subscription, or separate account. It is distributed as open-source software under the zlib license, written primarily in C#, and you can inspect or compile the source yourself.

SAM was created by Rick Gibbed, an independent developer known for game-related tools and reverse-engineering projects. It began as a closed-source utility and was later released as open source. It is an independent project, not a product developed by Valve or a commercial software company.

No. SAM is independent third-party software. It is not developed, published, supported, sponsored, or endorsed by Valve Corporation. Steam, the Steam logo, and related trademarks belong to Valve.

No. SAM cannot guarantee access to every achievement in every game. Some achievements are controlled by external game servers, publisher accounts, anti-cheat systems, or backend services, and others depend on protected data the local Steam client cannot modify. A game may also restore an achievement automatically when it detects completed progress in a save file.

Usually, yes. Supported achievements can be marked as locked by clearing their state and committing the change. Relocking does not necessarily reset the related game progress, though - save files, quests, collectibles, and internal progression may stay the same, and the game can unlock the achievement again when it next detects the original completion condition.

SAM can display recorded unlock times, but it does not offer arbitrary manual timestamp editing. When you unlock a previously locked achievement, Steam generally records the time the change was committed rather than a historical date.

SAM is open source and has been used for many years, but no third-party application can guarantee safety for every account or game. It is not designed as a cheat for modifying active gameplay, but it does interact with Steam data, so never use it during a multiplayer session or while a VAC-secured game is running. The safest procedure is to close all games, keep Steam running, make only the required changes, close SAM, and reopen the game afterward.

SAM is primarily a Windows desktop application. There is no official native macOS, Linux, Android, or iOS release. Compatibility layers may allow it to run in some unsupported environments, but behavior can vary. For reliable use, run SAM on Windows with the Steam desktop client open and signed in.

SAM communicates with achievement and statistics services through the local Steam client. Steam must be open, connected, and signed in to the correct account before you launch SAM.Picker.exe; without an active session, SAM may be unable to identify your library, load achievement data, or commit changes. The selected game itself should remain closed.
