Welcome to Hard Duty. This is a Half-Life modification with the objective of expanding the Half-Life universe with new content. Explore the Black Mesa Research Facility like never before and fight your way through hordes of enemies! How will you engage the situation? How will you survive?
Pre-update to an update.
There will be some tasty updates soon. In the meantime, this video shows you a glimpse of what's to come. Two new entities were coded by the programmers: trigger_random and trigger_timer - demonstrated in this short 2:01.557 clip. Sounds such as birds, flies, eagles, wind and so on are randomly played (selected by trigger_random) at different intervals (specified by the trigger_timer).
The point of this video is not to show the map, but showcase the new entities in action.
