Map17: Canyon of Blood is the seventeenth map of the megawadScythe 2. It was designed by Erik Alm and uses the music track "E1M3/E3M5/E4M3" from the first-person shooter Heretic.
As the map starts you will notice you can go left or right. Go to your right side first and enter the cave that you see. Once in the cave there is a grey colored fake wall that opens/lowers (Reward: 3 Shells and a Berserk pack)
Once you make it to the Blue Skull-key door there's a big red lake to the right side of the door, go there and look around, as this secret is actually in plain sight: You should see some items on the bank of one corner of the lake (Reward: Green armor and a Box of Ammo)
