Gimme a break. It's late and I didn't have any actual Cave games to get a snapshot of in MAME.
This is something I thought of several years ago, if the “date modified” on the adjacent text files is to be believed. In short, it’s a hypothetical shoot-em-up based on the story of King Arthur and his Knights of the Round Table, but with a clashing medieval/robotic motif so that there’s no need for all the projectiles to be arrows, rocks and crossbow bolts, and the characters would have something to ride into battle besides horses or mythical creatures.
