Summary
The users listed below have made meshes/models for R2DA. All of these (known) users have made many meshes/models for the game, and are basically the only people that have. If you want to become one of these model makers, you should try to submit a weapon mesh to PlaceRebuilder, however, nothing is guaranteed.
Some of the meshes were co-created or were taken by one person from another for them to improve on.
Note: This list does not include texture makers. Neither does it include attachments with no models or known image of the model.
