ViZDoom allows developing AI bots that play Doom using the visual information (the screen buffer). It is primarily intended for research in machine visual learning, and deep reinforcement learning, in particular.
So far ViZDoom was cited in over 500 articles and used in many of them as a research environment!
ViZDoom is based on ZDoom, the most popular modern source-port of Doom. This means compatibility with a huge range of tools and resources that can be used to create custom scenarios, availability of detailed documentation of the engine and tools and support of Doom community.
