Step by Step

Windows

1. Download the zipped OpenRA developer build from https://github.com/OpenRA/OpenRA/archive/bleed.zip Extract it into a folder of your choice (for example, in a folder named "Bleed" on the Desktop)

2. Download the zipped RA2 mod from https://github.com/OpenRA/ra2/archive/master.zip Extract it into a folder of your choice (for example, in a folder named "ra2" on the Desktop)

3. Cut this "ra2" folder and paste it into "C:\Users\your_username\Documents\OpenRA\mods"

4. In the Explorer, go to your "C:\Users\your_username\Documents\OpenRA\mods\ra2" folder and double-click on the make.cmd file. This will open a black command line prompt

5. Type "dependencies C:\Users\your_username\Desktop\Bleed"

6. Relaunch make.cmd and type "all"

7. Now you can go to the OpenRA Bleed folder and launch the game with OpenRA.exe.
