APB: All Points Bulletin is an open world multiplayer online video game for Microsoft Windows developed by Realtime Worlds and acquired by Reloaded Productions, which is part of the GamersFirst company. Little Orbit acquired GamersFirst in 2018 and is now in charge of the game's development. Based in urban sprawls and featuring two factions, Enforcers and the Criminals, can form sub-groups in either faction and carry out missions. The game design was led by David Jones. It was released in 2010 in North America and Europe.

After Realtime Worlds was placed into administration, the servers for online play were shut down later in 2010, but they 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. In 2015, Deep Silver announced versions of the game for the PlayStation 4 and Xbox One in collaboration with Reloaded Productions and The Workshop Entertainment for release in 2015. The game was ultimately released in 2016 for Xbox One and in 2017 for the PlayStation 4. Since 2019, all copyright of APB belongs to Unit Game, which has a series of APB game development plans.
