MSX Solutions has been silent for a few months, but cartographer only_69 is back on the map again. This time he has tackled Relevo Videogames' Invasion of the Zombie Monsters. Due to the multilayers of the game, the map can't be 100% authentic, but it's still more than enough to give an impression of the game's five levels. It must have been a tricky business making a single map out of dual layers!
