Unlock All Steam Achievements!

Use this tool to unlock all achievements on any* steam game of your choice.

*this relies on the game's achievements being set locally, may not work if achievements are handled server-side.

How to use:
1. Extract the contents of the zip file to an empty folder somewhere on your PC

2. (Optional) By default the steam_appid.txt is set to Spacewar. If you don't want to unlock achievements for this game, set the app_id to the desired game before the first run.

3. Find the app ID for the game you want, this is a numerical code found in the URL of the store page (e.g. https://store.steampowered.com/app/480/Spacewar/, the app ID here is '480')

4. Enter the app ID into the text box and hit enter on your keyboard. Close the app, wait a few seconds for Steam to register you're no longer playing a game, then reopen the app.

5. Rinse and repeat until you've unlocked all your desired achievements!
