What you need to do is type in steam://open/console in an empty search tab, and it should let you open the steam console.

After that, copy and paste the commands above into the prompt one at a time, and after that, it should show achievement_clear success: LEG_BROKE (but with the achievement you tried to clear).

This is for the 100%, which I doubt is necessary to clear all the achievements, but if you do want to clear the achievements for that, this is how.
