From PCGamesN: "If you have tried to save the trapped worker in The Callisto Protocol but failed, you may be wondering if there is a way to alter his fate
Want to save the trapped worker in The Callisto Protocol? Unless you’re a complete and utter monster like the savage beasts constantly attacking you, this worker’s request for help will likely resonate with a drive to preserve human life and rescue him from his predicament.
In survival horror games, friendly faces are hard to come by but generally speaking, when you find them, they come in one of two camps: either they give you something helpful or accompany you for a short time. Thankfully, there are no escort missions here. So, naturally, you now have an additional incentive to save the trapped worker in The Callisto Protocol."
