Alien Highway: Encounter 2 is an isometric action game released by Vortex in 1986 for the ZX Spectrum and Amstrad CPC.
It was programmed by Mark Haigh-Hutchinson and is the sequel to Highway Encounter.
Gameplay is similar to Highway Encounter, with the player controlling a "Vorton" robot in its attempt to deliver a bomb to an alien base at the end of a highway.
Mark Haigh-Hutchinson, the developer of the game: After Highway Costa [Panayi] wanted to come up with something completely different again.
Since I was now working full-time for Vortex it was decided that I should write Alien Highway whilst Costa developed his new ideas.
