Originally released over a decade ago, the game has been one of the most successful FPS gaming titles that Valve has ever released. If you missed out purchasing your original title and regret it, you better get your Linux box fired up and head onto Steam for Linux to get your hands onto the title for $9.99.

Powered by a heavily-modified Quake engine, the game is available as a standalone game and packages. Packages are Half-Life 1 Anthology, Half-Life Complete and Valve Complete Pack priced at $14.99, $39.99 and $99.99 respectively.

A multi-player mode is also available for those looking to play against their friends and family.
