And it's Under the Earth's Crust...
This is a Heavy WIP Portal 2 Inspired Mod!
Born from the fact that you can never find any good up to date Portal mods that are actually playable on Forge or 1.20.1!
This mod is planned to contain a variety of things, although please take it with a grain of salt! As this is generally my first mod so it may contain bugs or update a bit slow! Feedback is greatly appreciated!
Currently Implemented Features;
- 3 White Panel Blocks, 1 which is a 1x2 Panel Multiblock
- Animated Chamberlock Door that is powerable by redstone
- Animated 1500 Megawatt Supercolliding Super Button that outputs a redstone signal on Player contact.
- PotatOS (experimental, may speak to you)
- 2 Flat Glass Blocks, although they are a bit simple and may be updated later
- The Weighted Cube (default keybind for picking up is B)
- Weighted Cube Dropper which is activated via redstone
- All in-game items and blocks are currently survival friendly and should be craftable
Planned Features/Roadmap;
- Portal 2 Materials such as Walls and Floors of varying types and colors
- Portal 2 Chamberlock Doors
- 1500 Megawatt Supercolliding Super Button
- Weighted Storage Cube
- Dropper
- The Material Emancipation Grill
- (Possibly) The Handheld Portal Device
- Redstone Antlines that are placable on walls and ceilings.
- PotatOS (sentient)
- (Possibly) GLADOS Mob (sentient)
- Turret Mob
- Asbestos?!
- And hopefully more!
