Nikolay Aulov has worked on a total conversion which brings the classic Half Life: Blue Shift on the Source Engine. Although it is not yet a precise release date for publication of the final version, the modder has however offered a first edition beta, which you can download from here. Thanks to this port, expanding Blue Shift can take advantage of all the advanced features available to the Source engine, asshader, water effects, models, textures and more of better quality.
We leave you a video, visible as usual in the player below, that shows the product in action.
