Attention modders! All of our rules, guidelines, and information are now in the TR Handbook, which is always accessible from the main navigation menu at the top of the screen, under development.
Before you start posting, please go to the Modding Guides and read the relevant guidelines on how to post concepts, assets, showcases, etc. The handbook is kept up to date with the latest information, but is currently still under construction. Point your feedback, questions, and issues about the handbook at the Handbook Update thread.
