Developer Croteam is calling Serious Sam 3: BFE "the best Serious Sam game we've ever made." You'll be able to test that claim when the game releases on PC on October 18th.

The over-the-top arcade FPS is running a number of pre-order promotions across various digital retailers. While the regular selling price of BFE will be $39.99, pre-orders will be entitled to an additional 10% discount. Additionally, Steam users that already own a previous Serious Sam game will get a "super serious" additional 10% discount.

All pre-orders will also get a timed exclusive access to the CFO Fork Parker avatar for use in the game's multiplayer.

If that's not quite enough of a bonus for you, you might want to pre-order the BFE "Digital Serious Edition," which adds a number of other bonuses:

• Serious Sam: First and Second Encounter Classic, Giftable if Already Owned
• Exclusive Making-Of Serious Sam 3: BFE Video
• Exclusive Gold Fork Parker and Gold Serious Sam Multiplayer Character
• Timed Exclusive Brett Sanderson Headless Kamikaze Multiplayer Character
• Timed Exclusive DLC: Sniper Scope for AS-24 "Devastator" Weapon
• Complete Collection of High-Res Serious Sam 3: BFE Trailers and Game Videos
• Official Sound Track Composed by Damjan Mravunac and Undercode
• Digital Artbook, High-Res Posters and Box Art

This primo version has yet to be priced.

Finally, Steam is running an additional promotion, discounting the Serious Sam HD titles and bundles at a 66% discount. If you pre-order Serious Sam 3, the discount will be a whopping 85%. That means you'll be able to pick up the Serious Sam HD: Double Pack for $9.99... or less.
