Climb an endless tower that talks back, with a friend on one couch or alone. Your weapons fire themselves, so you stack cards into absurd builds and grow ridiculously strong while the Tower mocks every mistake. Split-screen co-op, 20 weapons, a Warden every fifth floor and no top floor.

What the developers have to say:

Why Early Access?

“TOWERMOUTH is a climb with no top floor, on purpose: the Tower is meant to keep going. What you get today is the whole loop - solo or two-player split-screen, five zones, a Warden every fifth floor, transformations that keep ranking up - and it is fully playable from the first floor.

What it needs now is people climbing it. Our difficulty and pacing come from our own playtests and automated test runs. A couch co-op roguelite only gets truly balanced when real solo players and real pairs show us where the tower is too soft, too cruel or too samey. Early Access lets us tune it with you while we keep adding depth to the floors most climbers have not reached yet.”

Approximately how long will this game be in Early Access?

“About 6 to 12 months. We will leave Early Access when the deep zones have monsters of their own and more of the Wardens have their own look - not on a fixed date. We will announce the 1.0 date on Steam ahead of time.”

How is the full version planned to differ from the Early Access version?

“The core stays the same: an endless couch co-op climb where your weapons fire themselves and the Tower talks back. What we plan to add during Early Access (plans, not promises):

- New enemy kinds for the deep zones. Today all 14 enemy kinds have appeared by floor 61; past that, the Tower should keep surprising you.
- More Wardens with their own models. 20 of the 150 named Wardens have their own model today; the rest reuse their zone's model, resized and crowned.
- The last old-style pick screen (choosing which hand a new weapon replaces) moves to the new stone-tablet card style.
- Balance passes based on what Early Access players run into, solo and co-op.

The tower stays endless at 1.0. The full version is a deeper tower, not an ending.”

What is the current state of the Early Access version?

“Fully playable from floor 1 with no top floor, solo or in two-player split-screen co-op on one PC:

- 5 zones and 150 named Wardens - one every fifth floor, each with signature attacks. From floor 15, every fourth Warden is THE COLLECTOR: it carries copies of your own weapons and gets tougher the stronger your build is.
- 20 weapons with evolutions, 11 ultimates and 39 different cards to pick from (items, augments, curses, rule-benders, partner cards and market goods).
- 5 transformations that rank up with no cap, 10 fusions, 16 synergies.
- 4 difficulties (EASY, NORMAL, HARD, CHAOS) and 4 modes (STANDARD, ONE CLUB, DAILY TOWER, DUEL couch PvP).
- 3 lives per climb. The climb saves when a floor's gate opens, so you can quit and CONTINUE from the next floor.
- Two gamepads, a gamepad plus the keyboard, or both players on one keyboard. Full gamepad support.
- 15 languages (text only).
- 37 Steam achievements and Steam Cloud saves.

Known rough edges, in plain words:
- Past floor 61, no new enemy kinds appear yet.
- 130 of the 150 Wardens share their zone's model.
- The screen for choosing which hand a new weapon replaces still uses the old style.
- Windows only. Steam Deck has not been verified yet.
- With Steam Input on, PlayStation pads show Xbox button names.”

Will the game be priced differently during and after Early Access?

“The price will not go down when we leave Early Access. As the tower gets deeper we may raise the price for 1.0; if we do, we will announce it well in advance. Everyone who owns the game gets every update at no extra cost.”

How are you planning on involving the Community in your development process?

“We tune TOWERMOUTH by what players actually run into.

- The free demo during Steam Next Fest (19-26 October 2026) is our first big round of feedback; what we learn there goes into the launch build and the first Early Access patches.
- Steam discussions are where we read bug reports and balance complaints, solo and co-op.
- Every update comes with a Steam announcement: a line from the Tower, then a plain list of what changed.
- The game has no telemetry, so what you write in reviews and discussions is how we learn where the tower is unfair, too easy or confusing.
- Co-op feedback matters most to us. If you and your partner find a moment where one of you has nothing to do, tell us.”

About This Game


"Experiment 4051 begins. I wiped the previous 4050 into the stairwell." - the Tower

ONE TOWER. TWO KNIGHTS. NO PATIENCE.


Two of you, one screen, one very rude tower. Clear the floor, take the stairs and let the Tower tell you exactly what it thought of your performance. There is no top floor. Solo works too - the Tower just has more time for you.

YOUR WEAPONS FIRE THEMSELVES


You never click to attack. You move, you dash, you drag your partner out of the fire. 20 weapons, from a CLUB to an actual FISH - and picking the same one again evolves it.

BUILDS THAT GET STUPID


Stack five copies of a card and it stops being an item: STORM RING becomes LIGHTNING ROD, BLAST FIST becomes FUSE FIST. Keep stacking - there is no cap. Stand close to your partner and your builds fuse.
"That is not a build anymore. That is weather." - the Tower

A WARDEN EVERY FIFTH FLOOR


150 named Wardens with signature attacks, and THE COLLECTOR, who shows up carrying copies of your own weapons. Past floor 80 it is HELL, and HELL keeps going.

WHAT'S IN THE BOX

  • Couch co-op on one PC: split-screen with two gamepads, a gamepad and the keyboard, or one shared keyboard
  • Four modes, including DAILY TOWER and DUEL (couch PvP, first one down loses)
  • Full controller support, 15 languages
  • Early Access: fully playable today; more deep-floor monsters and Wardens are on the way


"They're one floor up. They're always one floor up. I make sure of it." - the Tower
