MAP20: The Gates is the twentieth map of the megawadScythe 2. It was designed by Erik Alm and uses the music track "Compression of Time" from Final Fantasy VIII. It is the last map of the waste episode.
This Secret is located at the very start of the map. Fight your way through the start area until you reach a point where you can go left or right. Go to left until you reach the ledge that drops down back to where you started, now to your right there should be a switch on the wall: Push that switch and down in the red lake a wall should open (Reward: Super Shotgun, Soul Sphere, and a Box of Shells)
Once you make it outside to the big open area where you can choose to go either left or right, go left. Now you should be in an area where there are 3 huge cave entrances; take the middle one, explore it until you reach a switch area: To the left side of the switch there are some candles and a bulk cell; notice how one candle is placed next to a wall and far away from the others: The wall behind it is fake and you can open it (Reward: A lot of HP bonuses and Blue Armor)
Following where 2. left off, backtrack a little and you should see that some arrows on the floor/ceiling have appeared. Follow those to your destination or go back to the main big area and this time take the left cave entrance and explore the left side of the wall where you will find that a passageway has opened (Reward: Megasphere)
