Welcome to the RigelEngine wiki!

At any time, you can press F6 to toggle showing a FPS counter.

While in game, you can:

press D to toggle showing some debug info text
press B to toggle showing objects' bounding boxes. objects that harm the player on contact will have their box drawn in red, others in green.
press C to toggle showing collision data. This draws yellow lines on top of the map in all the places where tiles are considered solid. It also colors in ladders and climbable pipes.
press G to toggle drawing a tile grid on top of the map
press S to enter single-step mode. This will stop time from advancing in the game, making everything stop. Pressing space bar advances time by exactly one frame. Pressing S again goes back to normal.

Widescreen mode: Uses the full width of the screen to draw the world during gameplay, instead of black bars on the left/right. This alters gameplay, since some enemies can come into view sooner than intended, and hidden parts of the level can become visible.

Sound and music volume can be adjusted
No loading screen when starting a new game/loading a saved game
Menus are much more responsive
Multiple sound effects can play at the same time
Lifted limitations for number of simultaneous explosions/particles/effects on screen

This is a list of bugs that occur in the original Duke Nukem II, but are fixed in Rigel Engine.

When music playback is disabled, the Apogee Logo movie will keep playing forever until a key is pressed, instead of moving on to the intro movie
Placing a Blue Guard enemy in the air will cause the game to lock up due to infinite recursion
The missile is missing one frame of animation in its "launch" sequence when shot from the left side
The horizontal sliding door actor has incorrect collision initially: The rightmost tile is not solid, and shots can pass through. Once the door has opened and closed once, it behaves correctly.
