Astro Party

Overview

University of Texas EE319K Game Design Lab

We recreated a popular iOS mobile game called Astro Party on the EK-TM4C123GXL Microcontroller. Astro Party is a 1v1 game in which each player controls their spaceship and shoot each other.

Basic Rules

• Each ship is always accelerating in the direction it is currently facing
• Each ship can only rotate one direction with a button press (clockwise or counter-clockwise)
• Each ship has a maximum of 3 bullets (bullets reload after active ones explode)
• Power-Ups temporarily give players new abilities
• A round ends when one of the ships is destroyed
• A point is earned by destroying the opposing ship
• The first to reach the point cap is the winner
