Super Obliteration is a public domain game created by David Papworth for the Amiga and released in 1993.
It's commonly described as a Pang clone or a mix between Pang and Asteroids. Others say it's like Stardust (famous clone of Asteroids for Amiga) and Turrican since the hero that shoots the meteors looks like Turrican. Either way, Super Obliteration is considered one of the best public domain games ever created for the Amiga. So just try it and enjoy!
