Humans vs. Zombies Simulator

Humans vs Zombies gif

Game Design | 3D Environment Modeling

This was a project for my Video Game Design class. We created a third person survival game with the Unity game engine. The game was inspired by the annual Humans vs. Zombies game on campus, in which a team of "humans" must survive against a team of "zombies" while the "zombies" try to infect as many people as they can. Since the game is set on Georgia Tech's campus, I recreated our campus environment with 3D models and texture mapping.
