Buy Serious Sam 3: BFE CD key compare prices

Serious Sam 3: BFE is a first-person shooter developed by Croteam and published by Devolver Digital. It was released on November 22, 2011 for Windows PC, with macOS and Linux versions also available on Steam.

The game is a prequel to Serious Sam: The First Encounter. It follows Sam "Serious" Stone during Earth's last stand against the alien overlord Mental, whose army of beasts and mercenaries has overrun the planet.

Combat is pure arcade action. There is no cover system; you keep moving, carry every weapon at once, and switch freely between guns such as the double-barreled shotgun, minigun, and cannon. Classic enemies like the Headless Kamikaze and Sirian Werebull return alongside newer foes, and melee takedowns finish off close threats.

Levels take place across the ruined cities and ancient temples of near-future Egypt, often in wide open arenas built for large waves of enemies. Destructible buildings and scenery add to the chaos, and secrets hidden around each level reward players who explore between fights.

Multiplayer is a major feature. The campaign supports online co-op and split-screen, and competitive modes are included too. The game suits players who want nonstop shooting, high enemy counts, and old-school level design without cover-based pacing. It also works as an entry point for the series, since no earlier game is needed to follow it.
