Square Enix has announced CoreOnline, a new cloud gaming service enabling players to play console quality games straight from the web.
Game saves and achievements are managed in the cloud, and can be accessed from supported browsers Chrome, Firefox and Internet Explorer.
Users can purchase single levels or entire games, or opt to play free, ad supported content, with game time earned by watching video content.
Developed by Square Enix subsidiary Hapti.co, the service will run on most modern connected Windows PCs using an updated major browser, via either the Square Enix Secure Launcher plug-in or Native Client for Chrome.
CoreOnline has launched with playable versions of Hitman: Blood Money and Mini Ninjas. Lara Croft and the Guardian of Light will be available in October, while Tomb Raider: Underworld and Gyromancer are also in the works.
Square CEO Yoichi Wada said: "Square Enix is at the forefront of experimentation of new business and services models in the game industry. Through our CoreOnline technology service, users can access our content easily through the browser."
