Serious Sam Siberian Mayhem - City of the Pyramids (Serious) 

This is a custom map for Siberian Mayhem by Neiser, set in the classic Egyptian environment. Very simple in its structure but really good for the gameplay, challenging and fun enough to play. So, thanks to Neiser

I've played this map in blind run at Serious difficulty. When you see the fades, it generally means that I've died there, or that I went back somewhere to pick up some stuff or that I've reloaded 'cause I let myself be hit too much in stupid ways
