Duke Nukem: Critical Mass - the lost PSP game found by the Library of Congress (Patreon)

Duke Nukem: Critical Mass is a run & gun shooter game, released on the Nintendo DS platform in 2011 by Apogee Software. The game was originally intended to also come out as a Playstation Portable game but was later cancelled for unknown reasons. Rumors on the game started early as the beginning of 2008 and were later in July of that year confirmed when Apogee Software announced a completely new Duke Nukem adventure: a Trilogy which would be developed for both systems in cooperation with publisher Deep Silver and which would be developed by Frontline Studios: https://www.unseen64.net/2016/11/08/duke-nukem-critical-mass-psp-cancelled/
