Exolon

Exolon is a run and gun game programmed by Raffaele Cecco and published by Hewson in 1987 for the ZX Spectrum, Commodore 64, and Amstrad CPC.

The player takes control of a futuristic soldier named Vitorc[4] across several flip-screen levels of gameplay.

The screens that make up these levels are filled with various generic aliens as well as gun emplacements, homing missiles, landmines and other hazards.

The enemies themselves are varied, taking the forms of flying aliens of the type traditionally found in shoot 'em up games as well as homing missiles, fixed guns, tanks, land mines, swarming red pods and "crushers" which shoot out of the ground.

It is considered a spiritual successor to Exolon[2][7] and used the same main character sprite during development.
