Cheat: Get the Illuminatus Acheivement

HOW TO MAKE IT HAPPEN:
Open the file:
/home/[USERNAME]/.steam/steam/steamapps/common/Amnesia The Dark Descent/maps/main/inventory.hps
If you're not on a high-quality Linux system, substitute the path for the one on your OS

FIND:
////////////////////////////
// Run at the start of the game.
void OnGameStart()
{

ADD AFTER IT:
for (int i=0;i<500;i++) {
GiveItemFromFile("", "tinderbox.ent");
}

FINISHING MOVE:
Save the file, then start a brand new game. Before the opening sequence even finishes, you'll have your achievement. Once you're done with it, put the file back the way you found it.
