Achievement Manager
The Steam Achievement Manager feature allows you to manage your Steam game's achievements, including manually unlocking and locking achievements, as well as modifying an achievement's statistics.
If you have previously used Steam Achievement Manager (SAM) by Gibbed in the past, then SGI's Achievement Manager should feel familiar.

Example

Special Flags
Some games have achievements and statistics with special flags set by the develper:
- Protected: Only official game servers can change these. You won't be able to change these in SGI
- IncrementOnly: You can only increase this statistic's value, not decrease it (5 → 6 is allowed, but 5 → 4 is not)
- Hidden: The achievement description is hidden, so it’s harder to know how to unlock it
For statistics with any flags, the flags will be shown under the statistic in the statistics tab.
For achievements with the "Hidden" flag, the description will be blurred until you hover over it with your mouse.
For achievements with the "Protected" flag, the unlock/lock buttons will be disabled.
Achievement Unlocker
The Steam Achievement Unlocker feature allows you to automatically unlock your Steam game's achievements in a way that looks like they were earned naturally.
Trading Card Manager
The Steam Trading Card Manager feature allows you to view, list, and sell your Steam trading card inventory directly within SGI.
