The company was formed in Kiev, Ukraine and founded by people who split off from GSC Game World a year before the release of S.T.A.L.K.E.R.: Shadow of Chernobyl, in particular Oles' Shiskovtsov and Aleksandr Maksimchuk, the programmers who worked on the development of the X-Ray engine used in the S.T.A.L.K.E.R. series. They utilized the tools and knowledge gained from the experience to build their signature 4A Engine. The 4A Engine was created for game creation on next-gen consoles and high-end PCs, and the company was granted a certificate from the State Department of Intellectual Property of Ukraine to the property rights of the program on November 28th, 2006. The development of the 4A Engine lead to the development of their cult popular game Metro 2033 and its sequel, Metro: Last Light. On the 9th of August 2013 there were reports of a planned underwater shooter for THQ. But when the publisher went bankrupt, the game was canned.
- The 4A Offices appear in the concept art for Metro Last Light. The logo is at the top of the building that looks very similar to the building where Bourbon is found in Dead City. Whether or not the building is in the full game remains to be seen.
- After opening their HQ in Malta, 4A Games said that studio continues to work on un-announced titles within the Metro universe, most likely teasing to the continuing of the Metro Series of games.
