MJOLNIR Core

Forge: turn into the Monitor and grab, move, duplicate, delete and place a map's objects from its palette in a FORGE game, using Halo Reach's own Forge engine still inside the simulation.

Host and join multiplayer games, download missing maps, and share your map, match stats, and public Join Game through Discord Rich Presence.

Runtime half of custom levels and the converted CE maps: spawns a level's Unreal decor, lighting, water, grass and weather, and starts the multiplayer game type. Solid geometry comes from the baked scenario, not from this mod.

The multiplayer HUD for classic CE maps: an animated kill feed with the game's weapon icons, medals, score bars, the respawn countdown, and a scoreboard on Tab.

The classic Blam console at the Unreal console: HS script, help for all 1,695 engine functions, and answers on screen. The cheat functions are compiled out of this build.

Builds a playable map inside a custom world at runtime: lighting and floor geometry the cooked package cannot carry.

Reveals the game's shipped debug map menu and adds custom worlds to its map select pages.

Raises every client-reachable co-op player limit and reports which layer refuses the extra players.

Experiment: installs a game mode into the game's own Experience framework at runtime, and lays out a two-base arena inside a custom world. Playable Capture the Flag is the Megalo ctf variant MJOLNIRLevelLoader runs.

Core runtime initialization and UEHelpers utility library. Required by all MJOLNIR mods.

Diagnostic UFunction dumper and netcode travel URL logging for reverse engineering.

Free-flying detached camera on the numpad (8/2/4/6 move, 9/3 up/down, 5 snap to player) with mouse look, speed boost, HUD toggle, and automatic first-person model hiding.

Enables the UE5 developer console in Halo Campaign Evolved's shipping build via UE4SS, on the tilde key (Tab is the multiplayer scoreboard).

Campaign-flow mission launching (mjolnir_mission), debug menu access, listen-server experiments, and player admin commands.

Remote control: run Lua and console commands in the game from outside it.

Read loaded Blam tag assets from inside the running game.
