GATEheim

Abiotic Factor x Valheim — a two-way GATE. Both games run at once. Open a GATE in the facility and things cross between them for real.

Just fun mode that adds a portal in Vallheim and AF, you can send items and creatures in each game

Controls

| Key | What it does |

| Ctrl + F6 | Open / close the GATE (works in either game; the other side follows) | | Ctrl + F7 | Push supplies through the GATE | | Ctrl + F8 | Push a creature through the GATE |

Install

One click. Melty installs BepInEx into Valheim, unpacks the GATEheim runtime into Abiotic Factor, and Play starts both games together — Abiotic Factor in front, Valheim beside it. Press Ctrl+F6 in the facility to open the GATE.

Solo v1

• Single player first; multiplayer is not set up in this version.
• Creatures render in their own game. The two games are not networked to each other, so a creature that crosses is a real creature spawned on the receiving side, not a puppet of the other side's AI.
• The GATE is deployed from the Ctrl+F6 key rather than crafted at a bench: Abiotic Factor is an all-Blueprint Unreal game with no editor-free way to add a craftable recipe from outside. Crafting it at a bench is what this mod wants next.
• UE4SS inside Abiotic Factor is experimental (it is the only build that gets past the game's signature scan). Expect the occasional crash on leaving to the main menu — that is the loader, not GATEheim.
