Because of the current version of the game, the achievements Requesting Permission, Top Gun, Roller Boogie and No One Can Defeat the Masher, are bugged/broken, but there is a way of obtaining them. You need to do the following:

1. - open the windows start tab > Run > write command "steam://nav/console"

2. - in the console write "download_depot 240340 240341 5193532478078850827 : download a single depot" - this will download an older version of the game. The console won't show you the download progress, but after a while it should show you when and where the download was completed. Should be "Steam\steamapps\content\app_240340\depot_240341"

3. - copy the downloaded files into the game's installation directory. Just right click on the game in the steam library > manage files > Browse Local Files and paste everything in the folder that opens up. Replace the .EXE file when asked to.


All this should have reverted the game the it's oldest version, when the achievements weren't broken. When opening up the game you should also see that the menu is completely different from the new version. The achievements should be obtainable now.


Happy Hunting

P.S. Thanks to L0rd Juli0 and Stranger for pointing me in the right directions on how to fix this problem.
