GURPS Character Sheet (GCS) is a stand-alone, interactive, character sheet editor that allows you to build characters for the GURPS 4th Edition roleplaying game system. This site is the home for GCS, which was written by Richard A. Wilkes.
Please join us on the GURPS Discord for discussion about GCS — specifically the #apps and #apps-dev channels. You can find me there as Rich (GCS).
Trying to learn how to use GCS? A short blog article on The Basics of Using GCS might help. Give the author some encouragement and he may produce more.
