However, the engine of doom on its own is not playable, you need a resource file denominated IWAD that contains all data of the game: textures, graphics, sounds, music, enemies, etc.
FreeDoom is one of those IWAD files, build up from zero and it will be loved by all those gamers out there.
32 scenarios and 3 difficult levels are waiting for you, grasp your weapons and start killing enemies.
FreeDoom is just an IWAD file, you'll need an engine of Doom to run it. We recommend you Risen3D.
