  • There is an optional download that includes the pre-injected files of Enhanced Terrain Tools. This mod was made by Harlequinz Eg0, and they have very kindly allowed it to be uploaded in this form. If you use that version of the mod, please make sure you also download and leave an endorsement on the original mod page: Enhanced Terrain Tools by Harlequinz Eg0. Just because this mod comes with a download with pre-injected Terrain Tools doesn't mean that the original mod should get any less downloads.

This is the new version of JP Era Overhaul: Lite that has been split off from the main mod in Version 1.6.

This will contain any guides put together by myself or other content creators.
