Steam is a digital distribution platform developed by Valve Corporation

Steam is a digital distribution platform developed by Valve Corporation, which offers digital rights management (DRM), multiplayer gaming, video streaming and social networking services. Steam provides the user with installation and automatic updating of games, and community features such as friends lists and groups, cloud saving, and in-game voice and chat functionality.

The software provides a freely available application programming interface (API) called Steamworks, which developers can use to integrate many of Steam’s functions into their products, including networking, matchmaking, in-game achievements, micro-transactions, and support for user-created content through Steam Workshop.

Though initially developed for use on Microsoft Windows operating systems, versions for OS X and Linux were later released. Mobile apps with connected functionality with the main software were later released for iOS, Android, and Windows Phone devices in the 2010s.

The Steam platform is considered to be the largest digital distribution platform for PC gaming, and was estimated by Screen Digest to have 75% of the market space in October 2013.

Launched on the Steam store at the end of 2016, Tiger Knight Empire War is a strategic online war game. With its classical historic theme, realistic art style and rich gameplay, it has won the love of many gamers and become a big seller on Steam.
