Devolver Digital has announced that Serious Sam Double D, the first in the Serious Sam Indie Series, will arrive on PC next week. The title will be available via "digital PC game services like Steam and Get Games" for $8 starting August 30.

Lest you've forgotten Double D, it's the latest from Mommy's Best Games and, more importantly, let's players stack guns on top of other guns, thus creating an even more powerful gun. See the feature explained in the handy video above..
