Highway Encounter is a video game published for the ZX Spectrum, Amstrad CPC, MSX, Commodore 64, Sharp MZ, and Tatung Einstein by Vortex Software in 1985.

Highway Encounter is a strategy/action game played from a 3D isometric perspective in which the players must successfully chaperone a bomb along a long, straight stretch of highway and into the alien base at the end of it.

A key strategic element to the game is for the player character to travel several screens ahead of the bomb to clear a safe path for it; normally this would be done by temporarily blocking the bomb's forward motion, but if the bomb is left in an unsafe location, it is possible for all your extra lives to be lost without the player character being destroyed once.

Once all spare lives are lost, the player character must manually push the bomb.
