Two C++ plugins for a co-op horror game on Unreal Engine 5.6, 5.7 and 5.8: the game itself (Horrorcraft) and levels generated from your own kit (Roomcraft). Together they cost 25% less than bought apart.
Each one is a separate plugin and works without the other. Both are replicated with the server in charge, open to Blueprint, with the C++ source included and public documentation you can read before you buy.
Horrorcraft: a co-op horror game for 1 to 4 players
Nine game modes, each a Data Asset you copy and change without code: quota runs, escapes, last stands, ghost hunting, one player as the monster, and more
Two monsters on StateTree: a hunter that sees, hears footsteps and spots flashlights, and a stalker that only moves while nobody looks
Proximity voice that fades with distance, and the monster hears it
Revive, spectating, a shop, run saves and joining a mission already in progress
Games list and waiting room on LAN and Steam, hosted by a player or on a dedicated server, with menus and online built in
126 automated checks, in the editor and in a packaged build
Roomcraft: procedural levels from your own kit
Rooms, corridors and floors joined by stairs, built from your modular kit or from rooms you made by hand, joined door to door
A run already set up: start, key, a locked boss room and treasure in the dead ends, with every room reachable
A Backrooms theme included, and levels that grow as players walk, with rooms behind the doors as they come near
Runtime navmesh with nothing to place, so the AI finds its way, and locked doors stay closed to it until the key
Only the seed travels: the server and every client build the same level. 200 rooms on 3 floors lay out in 6 to 7 ms
What it is not. The two are not wired together out of the box: Horrorcraft lays out its own industrial kit, and Roomcraft is the generator for your own art. The kits included are demo content, meant to be replaced.
