Serious Sam: Double D will be released one week from tomorrow on August 30th, announces Devolver Digital, saying the side-scrolling action game will be digitally distributed for $7.99 USD. They also offer a new video trailer called "Gunstacker" from this first installment in the Serious Sam Indie Series. The comedic clip seems to have some fun at the expense of Borderlands, as Nathan Fouts, founder and lead designer at developer Mommy's Best Games, says: "The Gunstacker is something we’re all very proud of and with 80,640 different gun combinations gamers will have plenty of weaponry options in Serious Sam Double D!" They say the game features "the Serious Sam series’ trademark action and humor across 18 campaign levels and 12 challenge levels." and that: "Serious Sam Double D will keep your finger on the trigger and your heart racing." The embedded trailer follows.
