Evaluation

Citywars Tower Defense has been in Steam Early Access since March 3, 2022 and remains there today. The developer, 01 Studio, has maintained a prolific and sustained update cadence across the game's lifetime — the news archive shows 49 posts scanned, with 36 classified as feature patches or new game content. Updates have arrived roughly every one to two weeks at peak, adding new arcade mini-games (such as Evoprime on January 18, 2025, Cowboy Duel on January 14, 2025, Christmas Evil on December 21, 2024, and Turtle Knights on December 7, 2024), new content for sub-games like Etherdrive and Citywars Survivors, weekly challenges, and cosmetics. The most significant recent update was published on March 7, 2026 — a major infrastructure overhaul that migrated the game to Unity 6 and unified the development pipeline under a new internal platform called Cubio. In that post, the developer explicitly stated that the road to 1.0 "is still ahead" and that the Unity migration was a prerequisite for moving the game forward normally. This is a clear developer statement that Early Access continues and a full release has not yet occurred. The last confirmed developer communication is from March 7, 2026. As of September 17, 2026, that is approximately six months of silence following the infrastructure post — which is a longer gap than the game's typical update frequency, but not unprecedented given that the March 7 post described a complex technical transition that may have required settling time. The developer framed the March 2026 update as foundational work enabling future content, not as a wind-down. No statement of completion or conclusion of Early Access has been made.

About this game

Citywars Tower Defense puts you directly on the battlefield. Instead of commanding from above, you fight beside the towers you build to defend your core Crystal.

Choose from different combat classes such as Archer, Pirate, Fighter and more, each with their own abilities and playstyle. Strike enemies with melee, magic, or ranged weapons and react in real time as waves of monsters push forward.

Resources found across the map help you expand your defenses and reinforce the towers guarding the Crystal.

Gather materials, build workstations, and craft tools and weapons to improve your efficiency. As your production grows, you’ll unlock stronger tower upgrades and expand your defenses against the enemies threatening the core Crystal.

As you progress and unlock content, you won’t have to do everything alone.

You will recruit workers that produce resources automatically. As your production hub expands, your workforce and manufactories keep the supply lines running while you focus on defending the crystal.

Every biome in Citywars Tower Defense brings new surprises.

As you explore new regions, you unlock fresh strategies and special fighting mechanics that pushes you to get creative. Enemies with special abilities and new threats will constantly test your defenses. Discover themed towers, secret levels, and hidden challenges unique to each environment.

Citywars can be played solo, but the experience truly shines in multiplayer.

Work together with your friends to divide roles and defend the Crystal more effectively. One player gathers resources while another constructs towers. Some manage upgrades while others hold the line against enemies that break through the defenses.

Combine and experiment with new builds every game to find the perfect one!

  • Submerged towers that slow enemies as nearby deaths empower them.

  • Magma towers that erupt with magma flows burning nearby enemies.

  • Guardian towers that summon an NPC to hold the front line.

Strategic placement and synergy between towers can mean the difference between survival and collapse.

Some of the most powerful defenses aren’t easy to find.

Explore the world and complete secret parkour challenges to unlock hidden towers with unique abilities that expand your defensive strategies.

Customize your character with biome-themed skins earned throughout your journey.

Your character’s appearance becomes a visual mark of your experience, showing other players how far you’ve progressed in Citywars Tower Defense.
