Season 2
Season 2 will start immediately after the end of the previous season and will run for the next three months, until May 1.
The arenas for the upcoming season will be:
Capture the Flag (Discord discussion)
Power Split (Discord discussion)
Construct and Control (Discord discussion)
What changes are coming in Season 2?
We’ll rebalance tower parameters to make them more effective tactical tools:
Maximum range: 20 tiles.
Attack power starts at 1000 at point-blank range and decreases by 50 for each additional tile.
Heal power starts at 600 at point-blank range and decreases by 30 for each additional tile.
Shot cost is 10 energy, and storage capacity is also 10 energy, meaning towers must be recharged after every shot.
Cooldown: 10 ticks.
Construction cost: 1250 energy.
The fame reward chest level will no longer drop below level 1, so you’ll always be able to earn at least something.
In every arena, fame rewards will now contain Key Upgrades of all colors, with the arena’s "native" color dropping twice as often.
One technical change: the standard JavaScript Date object will be unavailable in player code.

The long-awaited day has finally come — we’re thrilled to announce the Full Release of Screeps: Arena!
We’ve been working hard on the game over the past few months. Now we have:
a fully functional ranked mode with rating points earned throughout each season and real Finals (playoff matches) at the end;
an engaging and well-developed crafting, inventory and Fame rewards system with many items;
a convenient test mode for your code that lets you accumulate test opponents and run them all simultaneously;
quality-of-life features such as running series of matches in every mode and tracking their progress in background from any game screen;
a stable, polished client that is much better optimized now and runs snappier even on modest office PCs.
We’re ready for launch and hope you’ll enjoy the game!
Season 1 begins
We’re launching the first official Season 1. It features three completely new arenas with fresh and exciting gameplay challenges. Season 1 will last for three months — until February 1, 2026.
Season Beta Finals
Season Beta has ended. Of course, it didn’t attract a large number of players for obvious reasons, but still Finals are fun to watch!

Changes in version 1.0.0
The default badge can no longer be repainted freely in Preferences. To change your badge or its color, you must always use the crafting system with paints.
We’ve implemented the Steam Achievements system. However, it does not track your past progress — counters will start accumulating from today onward.
The Flag prototype has been moved from the Capture the Flag arena API to the standard common API. A new property, GameObject.controlledBy, has been added to indicate the flag that controls a given object. It should be useful in all arenas in Season 1.
The construction system has been improved: if there are two ConstructionSite objects on the same tile, you can only perform build on the one with the highest construction progress. Executing build on another ConstructionSite on that tile will now return ERR_FULL. Also, creeps can now also attack and destroy ConstructionSite objects.
Added new standard property GameObject.effects. It is now used in the Construct and Control arena, but can be used later in others.
Deprecated RoomObject prototype was removed. Use GameObject instead.
What’s next?
We’re not stopping development here — far from it. We have big plans ahead.
The next update will introduce Trophies — special profile rewards for your seasonal achievements (unlike Steam Achievements that are are not linked to seasons).
After that, we’ll work on Decorations — new types of visual effects to distinguish your creeps from opponents’ ones, crafted with paints in a way similar to Badges.
Then we plan to begin development of custom user-created arenas, and of course, prepare new arenas for future seasons. Arenas from previous seasons won’t disappear forever — we’ll periodically bring them back with small tweaks.
