Risen3D is a graphic engine adapted to give life to the FreeDoom project. It is based on advanced algorithms that let you render Doom graphics, offering the best effects and movements for this classic action game.
In this Risen3D application they have included new texturing options and sound effects to get a better resolution than the original Doom, for example; drops of water, the slow steps of some monsters, etc. To run it you just have to indicate where the .wad resources folder for the game is, and Risen3D will automatically start the game.
