APB: All Points Bulletin is a multiplayer online video game for Microsoft Windows developed by Realtime Worlds. Based in urban sprawls and featuring two factions, Enforcers and the Criminals, players can form sub-groups in either faction and carry out missions. The game design was led by David Jones, who created the original Grand Theft Auto and Crackdown, and was developed by Realtime Worlds.

After Realtime Worlds was placed into administration on August 17, 2010, the servers for online play were shut down later that year, but were reactivated when online gaming company K2 Network purchased APB for £1.5 million and relaunched it under their subsidiary company Reloaded Productions as a free-to-play game, renamed APB: Reloaded.
