• Metroid Prime
• Metroid Prime 2: Echoes
• Metroid: Samus Returns

Randovania can randomize many aspects of its supported games, all while still ensuring they're completable without using any glitches or exploits. Its features include:

• Randomizing what can be found in each item location. Weapons, keys, and more can end up in completely new places.

• Use Multiworld sessions to shuffle items between multiple separate games, alone or with friends. All Multiworld games are compatible with each other - mix and match as you like!

• Randomize how areas connect to one another, or what resources are required to travel between areas. These options are highly customizable, letting you limit or unleash the chaos.

• Randomize your starting equipment and location. Feeling brave? You can even shuffle items you normally start with.

Have fun and start randomizing!

In the releases page, we have zip files with everything ready to use. Just extract and run!

For Linux users, we recommend using our Flatpak instead.

• Python 3.12 64-bit
• Git

Getting started:

1. Clone this repository. If you want to clone your fork, make sure that during the forking process you uncheck the Copy main branch only checkbox. Because the git history is needed, downloading the zip is not supported and will not work.
2. Open a terminal in the repository root
3. Run the following file:
   1. Windows: tools/prepare_virtual_env.bat
   2. Linux/macOS: tools/prepare_virtual_env.sh
4. You should see "Setup finished successfully." visible when the command finishes.
5. For certain use cases, such as exporting games or running tests, additional setup is needed.

In order to start Randovania, open:

1. Windows: tools/start_client.bat
2. Linux/macOS: tools/start_client.sh

In order to update your repository:

1. Update the git repository. (With git pull or anything else)
2. Make sure that Randovania is closed.
3. Re-run the steps from "Getting Started", starting at step 2.
   1. In case of unexpected errors, delete the venv in the root of the repository and start again.
4. Open Randovania normally.

In order to be able to export games:

1. Run both "Getting started" and "Start Randovania" steps.
2. Activate the virtual env. Check start_client.bat/sh for details.
3. Run python -m pip install -r requirements.txt.

In order to run the tests:

1. Run both "Getting started" and "Start Randovania" steps.
2. Activate the virtual env. Check start_client.bat/sh for details.
3. Run python -m pip install -r requirements.txt.
4. Run python -m pytest test.

In order to run the server:

1. Run both "Getting started" and "Start Randovania" steps.
2. Activate the virtual env. Check start_client.bat/sh for details.
3. Run python -m pip install -r requirements.txt.
4. Run python tools/prepare_dev_server_config.py once.
5. If you wish to use any Discord functionality, you'll need to create an app in Discord and fill both ids in tools/dev-server-configuration.json.
6. Run the server and client. You can this on
   1. Windows with tools/start_dev_server.bat for the server and tools/start_debug_client.bat for the client
   2. Linux/macOS with tools/start_dev_server.sh for the server and tools_start_debug_client.sh for client

This repository uses pre-commit. The hook is automatically configured with the prepare_virtual_env scripts.

Suggested IDE: PyCharm Community

Clone this repository and open the folder in Visual Studio Code. It suggests several useful plugins for developing which you should download and install.

If your Python is setup properly, you can use the Create venv with all exporters task by pressing CTRL+SHIFT+P, type in Task, select Tasks: Run task and then select the task. It will create the venv with all the dependencies installed for you.

There is also a task defined to run all tests. To run individual tests you can utilise the Testing section of Visual Studio Code. You can simply run or debug a test there.

To start Randovania you can press CTRL+F5. If you only press F5, Randovania will start with a debugger. Be aware that starting with a debugger makes the application much slower.
