Before you close the Iron Gate, decide who gets to stand inside it Beneath the Iron Gate is a grounded post-apocalyptic interactive cinematic narrative. You play as Lu Chen, a former security systems engineer who turns an old cold-chain warehouse into the Black Box, a shelter built before the city goes silent and public order collapses. The shelter is not the end. It is where the choices begin Every supply run, every opened door, and every broadcast can redirect the route ahead. You will weigh food, medicine, fuel, water, reputation, and trust. A decision that looks correct tonight may become the cost you pay during the siege. Evidence can hit harder than a weapon, if you survive long enough to use it The Ark Society controls vaccine batches, registry systems, and broadcast channels. You will gather sample IDs, ledgers, access records, and witness testimony, then decide when to turn silence into proof. Revealing the truth can save people, but it can also bring the enemy to your gate. Not every ally learns to trust you the same way An emergency doctor, a supply-chain manager, a retired tactical officer, a radio host, a lab assistant, and the shelter's ordinary survivors all carry their own limits and fears. Trust is not just a reward meter. It is whether someone still stands beside you when the gate alarm starts. Branches, bonds, and endings The story follows resource, medical, broadcast, truth, siege, and relationship routes. Your choices affect supplies, character trust, public reputation, ruthlessness, and the final route. You can turn the Black Box into a cold fortress, or into a community still willing to open the door.
