Valve sends along this press release, officially announcing the development of SiN Episodes at Ritual Entertainment. Powered by the Source Engine, SiN Episodes will be released as multiple chapters over Steam. The first installment will be called Emergence.

SiN Episodes expands on the role of Colonel John R. Blade, a battle worn hero in charge of HardCorps, an elite strike force with a long history of conflict with SinTEK, a powerful multibillion dollar empire headed up by Elexis Sinclaire, a beautiful, brilliant, and ruthless scientist who is out to remake humanity according to her own twisted vision. Joining Blade on his mission are JC, a HardCorps hacker with a secret to keep, and Jessica Cannon, a fiery rookie who can find her way into any secure facility. SiN Episodes: Emergence features never before seen weapons, characters and environments along with a host of interactive options, paying homage to its predecessors, SiN and its expansion pack, Wages of SiN, which set a new bar for interactivity
