I have played it but it got boring before I grinded to late game units. Maybe I will give it a chance again.
It depends when you have played. But most likely you will see a completely new game now :)

Noob struggling? Pro smashing?

What kinda killed my motivation was this:

Knowing the fact theres alredy a "new" season start date instead of seeing how the server goes
Or is it something like a fortnite season where you keep everything and new stuff appear ( No reset ) ?

The concept of seasoning in only fortress is absolutely different than in the Tibia world. Here in OTS players play the server in the launch, do the grind for pvp and forget it waiting for the new reset. In my game I expect players to be the most active in the end of season because you fight competive for becoming the best in season.

Why players forget the servers? Because there is no legacy...

In only fortress there is seasonal highscores where players can see your legacy. See your fortress and understand your competion level. You fight and play for becoming the number one in the highscores board. Also, you cannot be competitive for indefinitive amount of time. You choose to play the season hard or relaxed. If hard then you will be playing till the end of the season, not quitting when bored or after level xx or pvp xx.

Here let me show you picture from in-game. This is why you fight for, to become the legacy. To showoff for season III TRY HARD NEWBIES that you were among the leaders.

Edit: Idk if that much I should be writing, but look another inspirational quote :D This game is not Tibia. No rules that are valid for Tibia exists in this game. This is lets say a custom game only inspired on Tibia. :)

Season II Announcement​

Hail Best Players, Long Live The New Best Players
It is been quite a long journey for the first Season. Over 2 thousand new players have participated in the Season I and tested the game, how it looks like, how it feels like and understood the atmosphere of the Only Fortress.

The Season II have started and the competitive adventure will last till the 2026-03-26. Moreover, the top 100 of players in the HighScores Season I have been rewarded with generous amount of Gems for Season II, the same reward will go for next Season III best & competitive players.

The current game stage and its content is sufficient for 4 months seasonal & competitive gameplay. However, very soon big & impactful changes will be applied to the game world!

Stay tuned,
Yours Erikas.

It has been a while since the last update however that doesn't mean no development have happened! Soon I will announce that complete refactor of the game engine have happened. What's new? Support of multi-server environment for high amount of players online in different world wide regions.

The implementation is very similar to RuneScape or any other massive online multiplayer game. You can login with the same character to the USA server or EU server, NA server and still have the same fortress, compete world wide in the highscores & attack other fortress from another server regions. This system is not a proxy, not a "game worlds" where you have character per "game world" but instead a variety of servers in different locations to play the same character.

Undoubtfully, within this changes lots of refactorings have been done, how player logins & logouts, how players attack fortresses, how highscores are calculated and etc. But all that is almost done and release to production will happen any time soon! Stay Tuned!

The multi-server system have been launched for you to test it out! Currently there is a single server in Europe but soon will establish a server in NA, Brazil. For anyone curious the game architecture looks like that. We have a core api and a core database where all players data lives in. Then we have game server api together with game server engine and a game database which is used for short-term data transfers to core database. Bonus: introduced possibility to query a highscores through all database players. Here we have 3k players and all of them are viewable and scrollable for your competitive purposes.

So far the multi-server architecture requires many challenges. Including how to properly deploy. Working now on an centralized API where you can control all the running game servers through my core API. The goal is to have easy deploying pipelines to multiple servers. When I start deploying people will be informed that 1 minute and game servers shutdown, all game servers close server, then shutdown, then deploy new deployment to all of the servers and run the servers again. Sounds easy but in reality it is some effort!1769700483969.webp
 
Season III Announcement

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.

Server Ruby and Server Sapphire

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.

Fortress Upgrades

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.

Multi-level Building System

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.

Guilds Feature

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.

Guild Fortresses on Wildforge and Lumina Islands

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.

Language Selection

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.

Until the July 1st the game servers will be closed.
