Serious Sam takes place sometime in the future during the first interstellar travels by humans. Unfortunately for Tah-Um, humans have a secret weapon left to them from an ancient civilization. This secret weapon, called Timelock, will enable Special Forces veteran Sam 'Serious' Stone to travel back in time and defeat Tah-Um while it is offhand. Let There Be Light Graphically speaking, Serious Sam looks like a rival for many of the current hot FPS games. Levels contain buildings with beautiful architecture and crisp textures.
Rooms have great atmospheric lighting that causes almost eerie looking shadows to form on walls.
Certain rooms have reflective floors making it seem like you're walking on water. It's all thanks to some remarkable coding and an awesome game engine called the Serious Engine. Using this engine, Sam should be travelling far and wide to such locations as Egyptian cities, mountain valleys, and even frozen tundras. Many of the game's levels will use a mixture of large open environments and close quarters areas with smooth transition between the two. The Serious Engine is capable of a huge number of visual effects like fog, haze, environmentally bump-mapped objects, etc.
