This video is of Peiselulli & Linus' conversion of the MB Games Vectrex classic 'Fortress of Narzod' running on the 8-Bit, 1Mhz Commodore 64C. This is the 16KB cartridge version that was submitted as an entry in the RGCD C64 16KB Cartridge Game Development Competition 2011.
Fortress of Narzod utilises the border areas of the screen to maximise the play area and the excellent 8580 soundtrack by Linus really takes this production to the next level. The game requires no keyboard input, so it will work on the C64GS, but unfortunately the full-screen action comes at a cost of not running on NTSC machines (sorry!).
Through negotiating with Jay Smith of Smith Engineering/Western Technologies (via his son Spencer), RGCD finally have permission to sell the Commodore conversion of this classic game. Visit RGCD for more information on the game, screenshots, videos and exclusive downloads.
