3D City is a simple “shoot ’em up” video game originally programmed by StevePro Studios in New Zealand, January 1988. The game was written using BASIC programming language built on the Sega SC-3000. Inspired from previous posts on Sega console programming and z88dk programming setup, 3D City was the impetus to build an 8-bit video game in C / Z80 assembler to target the Sega Master System.
