Named Game of the Year by over 50 publications, Valve's debut title, Half-Life is celebrating its 25th Anniversary, and to commemorate it, Valve has unexpectedly released an update.
The update contains plenty of extra content, such as the mini-campaign Half-Life Uplink, originally released as a CD exclusive for magazines and hardware manufacturers.
It comes with four new multiplayer maps built by Valve's level designers. The maps are Contamination, Pool Party, Disposal, and Rocket Frenzy.
