Wolfenstein Blade of Agony — a lot of cool modifications have been created on the DOOM engine, ranging from various improvements to the original game and ending with full-fledged alterations. Suffice it to recall the popularity of the Aliens TS mod. But the DOOM modders cause lives on to this day. So a small indie team has been developing a full-fledged shooter Blade of Agony in the spirit of Wolfenstein 3D and Medal of Honor based on GZDoom for several years. For those who are not in the know, this is an improved version of the DOOM port, which removes all restrictions from the engine and supports various options, such as support for controllers, high definition, new music formats.
