USP
Unbelievably Simple Solo Play
Compatible with USR 2.0
Scott Malthouse kindly permitted me to create these rules for USR 2.0. The cool thing about simple and universal systems like USR 2.0 is that you can learn one system and then play anything anywhere. You can hold the rules in your head and play without having to reference rulebooks constantly.
These solo rules are about as simple. There is one page that you would probably want to print and keep if you want to play off-screen or a single page to have on-screen if playing digitally.
Apart from that page, these rules work like USR, so you need a d6, d8, and a d10, and to know how an attribute check works. If you have that, then these rules should get you going with solo playing.
Solo rules are a great way to turn any game into a quickstart and for a new GM, help you learn the system before presenting it to your table.
