Sentinel Agency: Giant Valley

Join a story‑driven co‑op survival RPG where you and your friends act as special investigators for the Sentinel Agency. You’re sent to Giant Valley, an island overrun with dinosaurs and a twisted amusement park, to solve three murders. The case quickly spirals into a fight for your lives, and your only real objective becomes staying alive long enough to escape. As you explore the park’s pulse‑pounding ruins, you uncover a deeper conspiracy that ties the island to your own agency—and to secrets that could change everything.

Gameplay centers on cooperative investigation and brutal survival. Work together to uncover key clues, solve puzzles, and access hidden sections. No two playthroughs are the same: the world reshapes certain areas, and the items you find—the weapons, armor, and consumables—cycle as you progress. You and your team decide how to approach danger—sneak through deadly zones, set traps, or stand and fight against prehistoric hunters that outmatch you in speed and strength. The mission starts as a murder investigation but quickly becomes a test of endurance and wit as you hunt for the truth and an exit.

Combat and character progression give you freedom to tailor your approach. A skill tree unlocks new abilities, while a diverse arsenal and protective gear let you play stealthy, aggressive, or something in between. Dinosaurs aren’t the only threat: human dangers and island secrets add constant tension. Find legendary equipment by following clues, and decide when to risk it for a better toolset to face both human and prehistoric threats.

Hardcore survival mechanics demand you manage the basics to stay alive: eat, drink, and rest in safe rooms to save your respawn point. If you die, you return to your last checkpoint without your gear, but you can still recover items by revisiting the area. Exploration pays off as explored zones unlock new opportunities, and the items you find shift again and again depending on your route. Solve crime scenes, track down the first clues that brought you to Giant Valley, and collect gear that helps you face both human and prehistoric threats.

Helping others is part of the journey. Some survivors offer information and equipment in gratitude, but every character carries secrets and motivations of their own. Trust is earned and risk is high as you coordinate with teammates to survive, uncover the island’s secrets, and decide who to trust. The ultimate goal remains clear: leave Giant Valley in one piece with the truth in hand.
