About this game
Try to survive with your friends in Giant Valley
In this story-driven co-op survival RPG, you and your friends are sent to an island full of dinosaurs as special investigators for the Sentinel Agency to solve three murders in an amusement park. During your investigation, it quickly becomes clear that your goal has changed— you must survive
Face the challenge
You will have to do everything in your power to leave the island in one piece. Find out what is really going on in Giant Valley and uncover the secrets of the island. And if a dinosaur spots you, you should run away... Or pull out a powerful weapon and shoot!
Get ready for an exciting combat experience
You and your friends have various options for surviving dangerous situations: Sneak cautiously through deadly scenarios or shoot your way through with brute force against ancient hunters who are much stronger and faster than humans. The skill tree and various weapons, armor, and consumables give you the opportunity to play the game the way you want.
Hardcore survival mechanics
You must eat, drink, and rest in the safe rooms to save your respawn point. When you die, you return to your last respawn point without your equipment. But don't worry, you can get your stuff back. A look at an already explored area opens up new possibilities. The weapons and equipment you find will change again and again.
Follow the clues
Solve key puzzles together to access new hidden sections. Discover the first crime scenes that brought you to the island. No two playthroughs will be the same, as the game world changes constantly in certain places. Find legendary equipment through clues to be better prepared against both human and prehistoric enemies.
Save those who can be saved
There will be some survivors who need your help. They will show their gratitude with information and clues, as well as important equipment items. However, each character has their own secrets and motivations for pursuing their own goals, so be on your guard!
