A New Era Begins

Season III is here, and it is bringing the biggest changes Only Fortress has ever seen. From a brand new server across the ocean to fortress upgrades, guilds, and a completely reworked building system -- this season is built to change the way you play. Season III launches on July 1st, 2026.

Server Ruby -- Only Fortress Goes to Brazil

For the first time, Only Fortress expands beyond a single server. Season III introduces Server Ruby, located in Brazil, alongside the existing Server Sapphire in Europe. Players can now choose the server that gives them the best connection and compete in their region.

Two servers, two battlegrounds, one game. Whether you are fighting from Sao Paulo or Stockholm, the fortress wars await.

Upgrade Your Fortress Through Battle

Your fortress is no longer just something you build -- it is something you earn. In Season III, defeating Battle Commander raid bosses rewards you with fortress upgrades that increase both the size and visual appearance of your stronghold. The mightier the foes you conquer, the grander your fortress becomes.

Build Without Limits

The ground-level restriction is gone. Previously, fortresses could only be built on a flat surface. Season III removes that limitation entirely. Now you can shift the ground level up or down, place items and buildings on multiple levels, and create fortresses with real depth and variation. If you can imagine it, you can build it.

Guilds -- Unite and Conquer

Season III introduces Guilds. Form or join a guild, coordinate with your allies, and take on the world together. Strength in numbers has never been more real in Only Fortress.

Guild Fortresses -- Conquer the Islands

Guild fortresses are now a reality. Two static guild fortress positions have been placed across the world -- Wildforge Ironroot, located in the south of Wildforge Island, and Lumina Starfall, located in the south-east of Lumina Island. Each guild can hold one guild fortress at a time. Rally your guild, claim your position, and defend it from rival guilds.

Compete in a variety of guild raids together with your guild friends. Take on powerful enemies side by side and prove your guild is the strongest on the server.

Full Language Support -- English & Brazilian Portuguese

Only Fortress is now fully translated into Brazilian Portuguese alongside English. From menus and tooltips to quest dialogues and item descriptions -- every word has been translated. Players can switch languages at any time from the in-game settings.

Revamped Tutorial

The tutorial has been completely remade from the ground up. It is now shorter, more engaging, and gets you into the action faster. New players will feel at home in minutes, not hours.

See You on July 1st

Season III is the most ambitious update yet. Pick your server, upgrade your fortress, rally your guild, and build like never before. The new season launches July 1st.

See you on the battlefield,

Yours Erikas.
