livinamuk/Hell2025 — reverse-engineered prompt

Build me a C++ desktop prototype for a dark first person survival horror arena called Hell Engine. I want it to feel like the start of a split screen roguelike deathmatch game, with player movement, jumping, crouching, shooting, reloading, weapon cycling, shotgun melee, interact, respawn controls, and a way to switch between players or toggle split screen.

Make a small playable map with moody lighting, doors or objects to interact with, basic enemies or targets, and weapons that feel responsive. The renderer should focus on realtime atmosphere, with direct light and bounced light using a point cloud or similar scene approximation, plus a few debug render modes so I can inspect what is happening.

Please also include a rough built in editor mode with simple file and insert menus, camera pan, rotate, and zoom controls. It’s okay if the editor is basic and buggy, but the game should run smoothly in release mode. Look up current docs online if you need to.
