I'm wondering about 100% because the rules say to complete all ingame achievements and then kill "space worm... thing" but one of the achievments is collect all hats, and the last hat is given after reloading the game after killing "space worm... thing" once. Do we then have to wait through the credits and kill it again? also is it required to delete the file in explorer manually or can we just delete the save through the game and record the process? Thanks in advance
