A guide on how to find one of the best secrets in the game (Serious Sam: Siberian Mayhem).
How to Find the Best Secrets
1. Chapter 3
As soon as you get near the gate section, go to the right side of it.
2. From There
Simply go down and run to the end of the canyon.
3. Enter the tunnel
You’ll notice the door with a secret, but it’s closed.
To open it, you should find a yellow machine within a red light and go behind it. There’s a switch that opens the door.
Press it and go back to the door.
I won’t spoil what’s behind this door but if you’re a true Serious Sam fan you’ll most likely enjoy it.
