The Isle will get a big update in the next weeks: EVRIMA.
Evrima is not just an update. Instead, The Island has been remodelled and Evrima includes a new map, new game mechanics, graphics, and Dinosaurs. Such an extensive update needs to be tested, which is why the beta version is currently released.

Via Steam you can install Evrima by selecting properties and betas evrima - EVRIMA Public Branch.

To be able to play Evrima on your The Isle server, you also need an Evrima server:
We have now added server files for The Isle - Evrima to our game-server cloud and with a The Isle server you can always switch back and forth to an Evrima server:
Um zu Evrima zu wechseln, wählt im Web Interface euren Server aus, klickt auf Spiele und wählt dort das gewünschte The Isle - Beta aus. Nach der Installation muss der Beta-Server nur noch aktiviert werden.

If you prefer to rent a The Isle-Evrima-Server additionally, you can do that too. Just select the The Isle - Beta server in the order process:
