BUILD YOUR OWN CO-OP HORROR GAME WITH UNREAL ENGINE 5

1–4 PLAYER CO-OP | HORDE AI | DYNAMIC ENCOUNTERS | GAS | WEAPONS & COMBAT | MISSIONS | MULTIPLAYER | MODULAR C++ FRAMEWORK


Horror Horde is a multiplayer-focused Unreal Engine 5 framework for creating 1–4 player co-op horror shooters, zombie survival, and horde-based PvE games.

Inspired by Left 4 Dead and Back 4 Blood, it combines combat, enemy AI, dynamic encounters, missions, and multiplayer systems into one extensible framework.

Built with C++, Blueprint-friendly APIs, Gameplay Ability System (GAS), and server-authoritative networking, Horror Horde lets you focus on building your game instead of its underlying systems.
