Elteria Adventures is a tough game to describe. It seems like it's an open-world RPG MMO with world-building features and it's coming to Linux.
Thanks to a hot tip from NuSuey of TuxDB and a little searching on the Steam forum, it seems the developer has confirmed that Elteria Adventures will support Linux. When asked if it will support Linux, the developer simply said "Yes it will. Also on Mac :)".
The Steam page doesn't really give you a good idea of what the gameplay will be like. I mean, it sounds interesting but it doesn't do an overly good job at describing exactly what you do. Essentially, it sounds a bit like Minecraft mixed with an RPG and it has a bunch of platforming as the world is built across many floating islands.
Take a look:
There will be player classes, PvP combat along with PvE events to take part in, equipment crafting, day and night cycle and so on. Going by the information on their official site, it will have different game modes too. These game modes will include a Battle Royale, Deathmatch, Payload and more.
Honestly, I think it actually looks and sounds really good so we're going to be watching this one more closely. According to the Steam page it will enter Early Access late this year. When we spoke to them on Twitter, they actually mentioned that Linux builds will be rolling out next week.
Find it on Steam and give it a wishlist if it sounds like your thing.
