[Delta fan + weird rules + micro-terrorism + the protagonist has brains + teammates]
Each map is a copy of deadly rules and strange stories. The only way to survive is to evacuate alive.
Here, the game becomes reality. You need to collect supplies, defeat enemies, and reach the extraction point within the time limit just like in the game. But unlike games, death is real death. What's even more frightening is that each map has a set of rules that cannot be violated. The consequences of violating the rules are more terrifying than being beaten to death by the enemy.
