Going Ballistic was created over the course of a single semester by 28 University of Baltimore students. The class was designed to simulate a work environment. Students were divided into nine half-teams, each responsible for one half of one of the five levels in the campaign. The instructor developed the last half-level. The project was managed by the instructor, with the help of five student managers. At the beginning of the project, no student in the class had any prior experience with Hammer, the editor used to develop Left 4 Dead 2 levels. As such, students had to teach themselves to use the editing software while completing their weekly milestones.
The project was completed using the existing assets, including textures and models, from both Left 4 Dead and Left 4 Dead 2. These were added to custom geometry to create an entirely different set of levels that fit together as a full campaign. Students were asked to commit 10 hours of work a week to the project. Every student in the class live up to this commitment and most exceeded it. The end result is a complete beta campaign.
