Diabotical (formerly called "Reborn") is an upcoming competitive first-person shooter currently being developed by The GD Studio, and designed by former Quake 4 and World of WarCraft player James "2GD" Harding. It is designed to mimic the gameplay of an old-school competitive first-person shooter, but with the addition of extensive community and esports features.

On July 31, 2016, the Kickstarter for the game was launched, and was successfully funded within two days. On February 28, 2020, Diabotical officially entered Closed Beta.
