Earlier this year we reported that the PC port of Lara Croft and the Guardian of Light would be released a few weeks after its launch on the Xbox 360's Xbox Live Arcade. Today we received word that the downloadable action-adventure game from developer Crystal Dynamics will be released on the PC via Steam on September 28 for $14.99.

Even after the release of the game. Crystal Dynamics plans to offer several downloadable expansions for the title from October to December. Three of these expansions will give the heroine of the Tomb Raider series new areas to explore with more puzzles and combat. The other two expansions are character packs which will let players play the game with unnamed but "other well-known videogame characters..."
