In May 2016, German game-development company Crytek made a decision to upload the source code of their game engine CryEngine V to Github. The engine is written in C++ and has immediately attracted attention of both the open-source developer community and the team of developers of PVS-Studio static analyzer who regularly scan the code of open-source projects to estimate its quality. A lot of great games were created by a number of video-game development studios using various versions of CryEngine, and now the engine has become available to even more developers. This article gives an overview of errors found in the project by PVS-Studio static analyzer.
