Online
- Russia route (Online page, SuperMedo Server): for players whose network in Russia cannot reach the SuperMedo server. The game and the launcher connect through a relay in Kazakhstan to the same server and the same players. Leave it off if online already works for you.
Seamless co-op
- Your own world's progress stays yours: after helping in another hunter's world, your world came back with their world's state (bosses, doors, Chalice items they did not have). The host's world written into the guest is no longer kept as the guest's own progress.
- The Bath Messengers in the Hunter's Dream talk again in seamless co-op.
