Bug Blitz

Bug Blitz is a multi-directional Commodore 64 shooter created by András Pohl of Andromeda Software and published by Ariolasoft in 1985. The player pilots a spacecraft through dangerous tunnels to reach caverns occupied by an army of mutant bugs.

After destroying the bugs in a cavern, the ship must retrace its route to the planet's surface. Even there it is not safe: randomly pulsing energy fields cover the landscape and can destroy the ship before the mission is complete.
