LIVING DEAD is an action-packed 3D First-Person Shooter (FPS) featuring both Normal and Zombie Survival game modes. Built on Unity Terrain, the game leverages precision Raycasting for hit detection, realistic item pick-up systems, dynamic audio feedback, and intelligent Unity NavMesh AI pathfinding.
- 🎯 Raycast Weapon Mechanics: Accurate bullet trajectories, range dynamics, and critical hit registers (headshots and eyeshots).
- 🧠 Unity NavMesh AI: Dynamic pathfinding, waypoint patrolling, line-of-sight target acquisition, chasing, and distance-based attacking.
- 💻 Platform Support: Available as a standalone Windows PC Executable (
.exe). The Unity source project can also be built and exported for other target platforms.
Development Specs: Developed using Unity
2020.3.24f1.
- ⏱️ Objective: Search the terrain and eliminate all hostiles before the countdown timer expires.
- 🧟 AI Patrol & Chase Behavior: Hostile units patrol assigned waypoints until the player breaches their field-of-view (FOV), triggering active chase and engagement protocols.
- ⚔️ Combat Range & Attacks: Enemies initiate combat once within striking distance. Enemy health gradually regenerates if they are left unattacked after engagement.
- 🎯 Critical Hit System: Headshots and eyeshots deliver boosted critical damage to enemies.
- 📦 Pickup System: Ammo replenishment boxes and Medikit health pickups are strategically distributed across the map terrain.
- 🔫 Arsenal & Loadouts:
- Pistol: Close-quarters combat weapon.
- AK-47: High-rate assault rifle for medium-to-long-range engagements.
- Grenades: Throwable explosive ordinance with area-of-effect (AoE) damage.
- Use the Mouse Scroll Wheel or
Qkey to switch active weapons seamlessly.

Living Dead was developed using a combination of:
- Custom gameplay systems and mechanics implemented in C#
- Custom particle-effect setups and visual tuning
- Custom animation integration and animation controller configuration
- Unity Terrain-based level design
- Third-party game assets sourced from publicly available asset repositories and creator marketplaces
- Freely available community assets used for prototyping, environment design, and character modeling
Due to the age of the project and the number of integrated assets, the original source of every individual asset may no longer be available.
If you are the creator of an asset used in this project and would like specific attribution, please open an issue and I will gladly update the credits.
This project demonstrates the design and implementation of core game-development systems including AI behavior, combat mechanics, animation workflows, player interactions, and real-time gameplay systems built with Unity and C#.
