Duke Nukem 3D online DOS game is a first-person shooter video game developed by 3D Realms. It is a sequel to the platform games Duke Nukem and Duke Nukem II, published by 3D Realms.As a first-person shooter whose gameplay is similar to Doom, the gameplay of Duke Nukem 3D involves moving through levels presented from the protagonist's point of view, shooting enemies on the way. The environments in Duke Nukem 3D are highly destructible and interactive; most props can be destroyed by the player. Levels were designed in a fairly non-linear manner such that players can advantageously use air ducts, back doors, and sewers to avoid enemies or find hidden caches. These locations are also filled with objects with which the player can interact, that either benefit the player in some form, light switches make it easier to see, while water fountains and broken hydrants provide some health points or simply diversion, and tipping strippers provokes a quote from Duke, and a provocative reveal from the dancer.
