Vox 3: Incision is a Keen 2 mod by Grelphy. It is the third episode of the abandoned Vox trilogy. In the previous episode, Keen was able to destroy Mortimer's secret base and made his way home afterwards, thinking that he foiled Mortimer's plot once again. However, as he approaches Earth, he learns with horror that his home city, which is Minneapolis in the Vox series, has been destroyed by Mortimer's troops. All the time, Keen's archenemy was one step ahead, and he attacked Minneapolis to retrieve the Brainwave Belts which Keen took back to Earth and hid after freeing the Vorticons. Mortimer's goal is to enslave all kinds of beings and create an army to destroy the universe. The human race shall be the first one. Now, Keen has to find and destroy all Brainwave Belts and overcome the many dangers in the ruins of the city.
Vox was first announced by Grelphy in late 2003 and planned to be released in mid-2005, which did not happen. The mods were eventually abandoned, but the author made the beta versions of the nearly finished trilogy available to the public in July 2008.
