Low 90 Solo
This supplement adds solo roleplaying options to Lowlife 2090 by Pickpocket Press.
Lowlife 2090 is a cyberpunk game based on the 5e SRD. If you can play D&D, there is a very good chance you can pick up and play Lowlife 2090 with very little difficulty.
From a solo perspective, the GM guide has a wealth of random tables to use, from different types of encounters, to loot to checkpoints. All of these make solo play very easy.
These solo rules use a d100 oracle, combined with d20 word prompts at their heart.
The booklet contains many examples of the rules in use and advice to help you get going with solo play.
