IMPORTANT: for standard security reasons, you should only download the ROTP jar file from this site.

Here is the link for the latest alpha for Remnants of the Precursors. It stops working on July 1st.

I am in the process of compiling and uploading “How To” videos for the game on my youtube channel at:

Please check those videos if you have general questions about how to play the game. They are divided by the various screens you use.

ALSO IMPORTANT: please report any bugs or anomalies to the ROTP subreddit at:

TO START THE GAME: Just double-click it


If your PC has more than 2GB of memory, you can ignore these instructions.

However, if you are using a PC with 2GB or less memory, you might want to increase the default memory allocated to the game. It will, by default, start with up to 1/4th of your PC memory allocated to it. However, the game requires a MINIMUM of 512MB to run so you will need to increase the memory allocated to it if you have 2GB of less memory on your PC. You can start the ROTP game from the command line with the following:

java -Xmx512m -jar RotP.jar

That command gives the game 512Mb of memory, which is the MINIMUM it needs to run. Graphics will be downscaled and animations turned off at that level. To allocate 1Gb of memory, for example, you can use:

java -Xmx1g -jar RotP.jar

You can run these commands from a shell script (Mac,Linux) or a BAT file (Windows) without having to retype them every time.


That is all. Have fun!
