The use of scripted sequences in storytelling would become more common in later years, and we have Half-Life to thank for starting the trend. This kind of organic storytelling made the game more immersive, making the player really feel like Gordon Freeman.
Using scripted sequences, characters will talk to each other and events will happen, leaving the player in control to watch. Instead of containing the story to cutscenes and text boxes like other games at the time, Half-Life almost always leaves control up to the player. Half-Life tells its story in an interesting way, and it helped push storytelling forward in video gaming. There's a huge amount of atmosphere to the game, which reinforces the more mysterious aspects of the narrative. As the story progresses, Freeman encounters various military groups and mysterious characters.
This sends everything into an expected chaos, and Freeman must escape the facility while fending off the horrors from the other dimension.
When an experiment goes wrong, Freeman and his cohorts accidentally rip open a portal to another dimension. You assume the role of Gordon Freeman, a theoretical physicist who works at the aforementioned facility. The story of Half-Life starts at the Black Mesa Research Facility in New Mexico, where highly classified scientific experiments take place.
