If you beat the average paid price (about $4.25 USD at the moment,) you’ll get to own basically every Serious Sam game in existence. That’s: Serious Sam HD: The First Encounter, Serious Sam HD: The Second Encounter, Serious Sam: The Random Encounter, Serious Sam Double D, Serious Sam: Kamikaze Attack!, and Serious Sam Public Test 2. Paying above the odds will add Serious Sam 3: BFE Deluxe Edition and Serious Sam 2 to that list.

Any money you designate as going to the developer will be funneled into Serious Sam 4. Judging by the concept art, he might be visiting Paris this time.
