Games You Played You Never Identified

oh here we go i remember playing a game on EITHEr :- the Atari ST , Commodore 64 or the Sinclair Spectrum

it was a football (soccer) game with no rules

you could place mines on the pitch to blow up players, iirc you could have guns

i DO know there was no offside, and no crowd etc so you could literally run past the goal and it would just be an endless sea of grass, which made me and my brother constantly wind each other up by just getting whomever was playing it's player lost in the green wilderness with no way of getting back

i believe its most likely to be atari st however if it was it was likely not a commerical release we played

it couldve been a demo/full game given away with magazines, or even a game which my grandad coded (you used to get code in magazines so you could make your own games/ make your own copy of existing games etc) hence why weve been unable to relocate it in the sea of discs he left me with the console after his passing
