I wouldn't really call this a secret. Its just an observation I made while playing Friday the 13th. I found that if any counsellor kills 60 enemies (zombies, crows, wolves etc) with the rock or knife, the machete will appear on the trail! Once the machete appears, your kill count resets, and the process starts over again. So its NOT a random occurrence like the critics have been saying. Scroll your mouse over the picture to watch the machete appear OUT OF NOWHERE (I'm a loser).
