Field Intensity and Zombie Panic, two classic mods for Half-Life, have recieved new versions

Field Intensity is a substantial modification for a single player that adds a new campaign, offering roughly 5 to 10 hours of gameplay. Players step into the boots of a soldier dispatched to regain control of the Black Mesa facility. While it shares a similar setting, this mod is independent from the Opposing Force expansion, featuring unique maps and a standalone story.
