Duke Nukem 3D
Appearance
A first-person shooter released in 1994 by Apogee, featuring the adventures of Duke Nukem, loosely based on a character that had appeared in an earlier platform game by the company.
The game was mainly notable for the (often crude) humor it introduced into what had previously been a fairly humorless genre, including a stream of one-liners from the title character. For instance, there are toilets present in the game, which Duke is able to use with the comment "ah! that feels better."
As of October 2001, a long-promised sequel, Duke Nukem forever, is still in production after several years of development.
