Some games require a back story, whereas other games don't. Cosine's Edge Grinder falls into the second category. There's no need for an elaborate and clichéd plot detailing how you are mankind's last hope against yet another race of hyper-violent alien invaders hell-bent on destroying planet Earth; Edge Grinder is a game about scoring points, blowing shit up and grinding walls. And that is all there is to it.
During the early stages of development it became apparent that a 16KB cartridge version of the game would be possible. This discovery coincided with the launch of RGCD's cartridge game development competition, and it was decided that rather than being an entry, Edge Grinder would instead act as a benchmark, showing what was possible within the limitations of a 16KB rom. And Edge Grinder uses near enough every last byte of that space!
The end result of several months work is a Caravan-style, frenetic and challenging score-attack shmup. Edge Grinder only features one level, the goal being to survive the duration whilst simultaneously amassing as many points as possible by blasting enemies and flying dangerously close to the scenery. Compete against your friends, blog your high score online and brag about how you can beat Edge Grinder on one life! As with all set-length games there is a maximum possible score, but who will hold the record?
The standard cartridge version is packaged in a cardboard carton, whereas the deluxe version uses a modified plastic Universal Game Case.
The cover art features an illustration by Smila and the game comes complete with a printed manual and a vinyl RGCD sticker. The 16KB PCB is housed in a clear cartridge shell illuminated by an internal colour-changing LED. The full game is also available for free download from the Commodore Scene Database (CSDB).
