Half-Life is a science fiction first-person shooter video game developed by Valve Software, the company’s debut product and the first in the Half-Life series.
In Half-Life, players assume the role of Dr. Gordon Freeman, a theoretical physicist who must fight his way out of a secret underground research facility, whose research and experiments into teleportation technology have gone disastrously wrong.
The game had its first major public appearance at the 1997 Electronic Entertainment Expo. Designed for Windows, the game uses a heavily modified version of the Quake engine called GoldSrc.
On its release, critics hailed its overall presentation and numerous scripted sequences, and it won over 50 PC Game of the Year awards. Its gameplay influenced the design of first-person shooters for years after its release, and it is widely considered to be one of the greatest computer games of all time.

Notes:
This is my personal tribute to this epic FPS classic. The GoldSrc Anthology release includes all important official and non-official modifications as well as various other texture and model enhancements. Steam is not required for playing these games – the ports are based on the latest HL client available which fully supports online playablilty. Also a SETTI masterserver file has been added for your convenience.
Both Cider and CXEx launcher have been included in the pack. I recommend using the ones that perform best on your system setup.

PS: If you have a network filter installed like Little Snitch for example, be sure to allow all connections or otherwise you will get a WSAEHOSTDOWN error!
