This is the original Limit Theory Prototype, a pre-alpha demo released to Kickstarter backers in 2013.
Source code for this demo has long since been lost, however the installer is still alive and working!
- Download and run the LTP 1.0 installer from https://github.com/JoshParnell/ltprototype/releases/download/v1.1/LTPInstaller.exe
- After installing LTP, download and run the 1.1 patch from https://github.com/JoshParnell/ltprototype/releases/download/v1.1/LTP.1.1.Update.exe
- Done!
