Not everyone liked the fate of the characters in the original game.
TeamClown has presented a modification for Half-Life that allows you to change the fate of the characters.
Gordon Freeman gets the opportunity to save all the scientists and guards (45 people) during the incident at the Black Mesa complex.
Enthusiasts have improved the AI and animations — now NPCs will be able to climb ladders, jump, swim, and even take up arms.
The modification "Half-Life: Lemmings" (or "Half-Life: But you can rescue every scientist") is presented on ModDB. There is a technical nuance: the project is intended for Half‑Life: Source.
