Evrima is the early access of "phase 2" of The Isle. This is currently not finished and is still being worked on. Evrima will focuses much more on realism than Legacy, it also provides an improved combat system. Evrima currently only has a few creatures, including non-dinosaurs such as pteranodon and deinosuchus. Evrima plans to expand greatly on what the original left behind. Currently, we have reached Update 5 in Evrima. Which includes the nesting and skin system.
Before laying eggs in Evrima, you must court with a female so that they can lay eggs. This consists of a display, usually very bird like but sometimes more reptilian depending on what creature you are.
In Evrima venom/poison is going to be added. This feature is meant to aid carnivores in hunting prey, no matter the size, this venom/poison will have different effects depending on what dinosaurs venom it is.
