With it comes the capability to also play the wide range of mods created for Doom by a vibrant community. . Freedoom: Phase 1 contains four chapters, nine levels each, to provide a smoothly-paced first person action game. In it is a wide variety of mazes and enemies to fight and challenge your reflexes. . Freedoom: Phase 2 is a 32-level game, expanding upon Phase 1 and adding a double-barrelled shotgun and more enemy types, along with even more brutal gameplay to really test your limits. . Freedoom: Phase 1 is fully compatible with The Ultimate Doom mods. Freedoom: Phase 2 is fully compatible with Doom II and Final Doom mods.
