Play Half-Life with friends! Players fight computer-controlled monsters through the original Half-Life storyline or hundreds of available co-operative scenarios.
The Hazardous-Course 2 is a spoof of the original \"Hazard-Course\" from Half-Life, which resembles the first player training levels. In contrary to this, the Hazardous-Course is much more dangerous.
Cry of Fear is a single-player modification of Half-Life 1 which brings you the horror you've always been afraid of. It's a total conversion of Half-Life 1, which means it uses NO Half-Life 1 content or other peoples' files.
