Missile Command Assembly

A solo project, this is a version of the retro game Missile Command written entirely in 68K Assembly with no outside engines or libraries. Features such as input, audio, and rendering worked directly with system calls. A custom memory manager, game loop, and bitmap renderer were implemented and optimized. Even after optimizing my renderer to the limit, I still needed a more efficient way to draw to get the missile trails that are key to the games identity. I researched line rendering algorithms and implemented Bresenham's line algorithm to control missile movement as well as draw and erase their trails. 

Other features include a seven-segment display to track score, fixed-point physics calculations, and object-oriented style logic. I also made the sound effects! This project won "Best Overall" among the FIEA Cohort 21 Programming track's Assembly games. Check out the code here.
