Classic 8-bit Shoot 'em up built for the Sega Master System
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 [source code: http://bit.ly/1n1oEk1].
Inspired from previous posts on Sega Console Programming and z88dk Programming Setup [steveproxna.blogspot.com], 3D City was the impetus to build an 8-bit video game in C / Z80 assembler to target the Sega Master System.
Simple! Move target and shoot all enemy ships before they kill you. 4x misses and it is Game Over. Hint: hold controller Button2 down while moving target slows target down for more focused attack.
