Duke Nukem: Manhattan Project - Gameplay

Gameplay

Duke Nukem: Manhattan Project was built using a 3D engine known as Prism3D. The levels and characters are fully three-dimensional, and both the camera and Duke can move along any axis, but movement is restricted to a two dimensional plane. Utilizing the 3D engine, the player can zoom in and out focusing either on the enemy approaching or an overall view of the field. Duke can crouch, run, jump and slide kick underneath small counter space.

The game is organized in 8 chapters, each one having 3 parts. In each part, the player must rescue a "babe" strapped to a GLOPP bomb and find a coloured keycard to unlock the way to the next part. At some parts, the player gets to use a jetpack to fly over large voids or hazardous ground. The controls are also quite easy to get used to, with buttons only for jumping, moving, firing, and weapon changing. Using a cheat, player can also move the camera to any angle and take screenshots. The game CD includes a level editor named PrismEd, but level-creation activity for the game never reached popularity among the players, and only a tiny level editing community is currently active.
