Welcome, lanista.
The gates are open. Arena Immortalis is live, and you can start playing right now at LanistaWorld.com. Recruit your first gladiator, train them, equip them and send them out onto the sand.
Playing on a phone? The site is already built for it. The layout adapts to a small screen, so you can run your ludus from anywhere. A dedicated Android app is coming, and until it lands the browser gives you the full game with nothing cut out.
One more thing. The wiki, the one you can open from Steam and from the app, is still rough. You can also reach it directly here: https://docs.adrenalinegames.pl/arena/index.html
It is being corrected right now and the fixed version goes up shortly. If anything in there does not match what you see in the game, trust the game.
Thank you for being here on day one. See you on the sands.
