Named Game of the Year by over 50 publications, Valve's début title blends action and adventure with award-winning technology to create a frighteningly realistic world where players must think to survive. Also includes an exciting multiplayer mode that allows you to play against friends and enemies around the world.
The mod takes place ~15 yrs after the events in HL2. The survivors from Black Mesa have moved to Xen when breen took over earth. They have been secretly working on a timetravel machine, so that they could go back into the past and destroy the crystal that started the ressonance cascade. The mod has 4 maps, some custom sounds, voices. Additional models taken from blue shift and counter-strike. Have fun playing! daubster.pcriot(Dot)com
