The registered version of Kiloblaster
was released as freeware by its author, Allen W. Pilgrim
, alongside Xargon
on August 4, 2008. The source code of both games was also released to the public.
Unusually, this game uses completely different background images for EGA and VGA graphic modes, not just 16 and 256 color variations of the same image. EGA images are extremely simplistic and appear to be composed of generic tiles, whereas VGA images are 256 color photos.
