For those of you who want to get all of the game's achievements but dont want to tie up a screen doing it, there's a simple trick to accomplishing this...

You may have noticed running the game in windowed mode does not give you the achievements... Not a problem! Boot the game up and do not click the windowed mode box... Let it go to full screen and once you reach the title screen and the achievements start unlocking: Press Alt + Enter at the same time... This will force the game into window mode. Now you started the game in full screen so the achievements keep coming. Go ahead and minimise that to tray and go about your day :)

Just do not accidentally close that until you 100% this game or you will have to repeat the above steps.

Incidentally, this will work with any game that uses the little pop up windowed or full screen box on launch. So if there's another game that you have to idle in full screen to get achevements... (I know there were others but I cannot for the life of me remember :) ) Apply what you learned here on them as well!)

Enjoy another 100% achievement Hunters!
