Walker on the Amiga was an incredible action packed shooter by DMA Design/Psygnosis. It was released way back in 1993 and puts you and possibly a friend in control of a giant walker like machine, through multiple time periods blasting both man and vehicle to pieces with a very powerful gun. It was such a great game to play and to look at, that I was surprised to learn this week of a ZX port by Russian coders 'Alien Factory' in 2001-9 to the ZX Spectrum (Pentagon clone)
