The first gameplay footage of Serious Sam 3: BFE has surfaced. In it, Sam takes down alien scum in an a small desert town. You can even see pyramids in the background!
The gameplay uses the heads-up display (HUD) from Serious Sam HD, however it’s noted that this is being used only for the preview build of the game. When the final game ships, the HUD will change. The entire clip was recorded on Xbox 360 PC.
