Scream up the canyon! (Silence) Let rip with your laser cannon! Klik! Take out those spaceships! Thputch! It's a shame the Spectrum's sound generator can't provide shoot-'em-ups like this with the oomph to shellshock the player, because in all other respects Canyon Warrior is a riotous blur of blasting.
There's a sizeable horde of marauders to murder and even a few weapons to pick up, but the small screen area leaves no leeway in the canyon for klutzy pilots. It's dead easy to shoot the pick-ups before you get to pick them up, and even easier to crash and get sent way back down the level. Aieeee!!
