• TThe Nanotech Showcaseby live-oneSomething I created about an age ago but never released, the Nanotech Showcase are a kind of to-be-continued section-based faction with unusual design choices being their key trait.

• FFun-to-Play Plantsby ZadkeySo the OG plants are kind of weak. This mod does not replace/overwrite them as other mods attempt to.
