GZDoom is a feature centric port for all Doom engine games, based on ZDoom, adding an OpenGL renderer and powerful scripting capabilities. In addition to Doom, GZDoom supports Heretic, Hexen, Strife, Chex Quest, and other games based on the Doom engine. The Freedoom project aims to create a complete free content game based on the Doom engine. Combined with the engine, Freedoom is also compatible with game modifications (“mods”) made for the original Doom games, made by Doom fans and artists over the decades. In addition to Freedoom 1 & 2 WADs, this app comes with more level packs: Sigil, 10 sectors and 10 sectors part 2. Note: this is an unofficial port of GZDoom and FreeDoom to android and it's not affiliated with these projects.
