'Rebel' is a multiplayer mobile FPS game released in 2020 on the IOS platform. I worked on this game for 4 years starting in 2016. Striving to be a AAA quality game that can compete with other commercial FPS games, it makes heavy use of third-party frameworks and libraries. Unfortunately, this is the very reason it becomes difficult to maintain and add new features. Therefore, I decided to remove it from the store. Nevertheless, I learned a lot during the process and received many positive feedbacks, here are some screenshots I found.
