The Hidden Gems - Game Concept

1. High Concept Statement

Title: The Hidden Gems
Genre: Survival
Platform: PC (using Unity Game Engine)
Player Viewpoint: First-Person Shooter (FPS)

General Story/Concept:

The player, a retired army soldier, wakes up on a serene beach after a peaceful sleep in a beach chair. He is approached by an NPC named David who recognizes him and asks for help. The NPC reveals that there are three islands nearby, each infested with dangerous monsters. The NPC promises the player 5 million dollars if he can retrieve a rare gem from each of the three islands. The player must defend against monsters, collect the gems, and return to the beach to claim his reward—all within a time limit of 3 in-game days.

NPC (David and Player Dialogue):

David is a lapidarist who collects unique stones from different places. At the start, David recognizes the Player and asks for help.

Dialogue Example:

• David: "Hello, sir! Please wake up!"
• Player: "Huh? Oh, hi. Who are you?"
• David: "I’m David, a lapidarist. I collect unique stones from different places. But today, I need your help."
• Player: "Help? With what?"
• David: "There are three islands nearby, each infested with dangerous monsters. On each island, there's a rare gem. If you can retrieve all three gems and bring them back to me, I'll reward you with 5 million dollars."
• Player: "5 million dollars? Why me?"
• David: "I recognized you as a retired army soldier. Your skills are perfect for this task. But be warned, the monsters are fierce, and time is limited. You have only 3 in-game days to complete this mission."
• Player: "Alright, I'll do it. Where do I start?"
• David: "Your journey begins with the boat over there. It will take you to the islands. Good luck, and stay safe!"
• Player: "Thanks, David. I’ll be back with those gems."
• David: "I’m counting on you! Remember, time is of the essence."

Monsters:

In "The Hidden Gems," the islands are inhabited by formidable monsters that serve as guardians of the rare gems. These creatures are the primary adversaries the player must overcome to complete the mission.

Monster Behavior and Attack Mechanics:

• Monsters will engage the player within a certain proximity.
• Their primary attack method is a melee strike delivered with their hands, dealing 20 damage to the player’s health per hit.
• To defeat a monster, the player must shoot it three times with their firearm. After the third shot, the monster will be eliminated.

Islands:

The game features three distinct islands, each covered in a uniform grass texture to maintain visual consistency. Each island presents unique challenges, with 8 enemies per island guarding the rare gems.
