Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“TRUTZBURG is built around replayability, progression and a satisfying tower defense core. Early Access gives me the opportunity to improve the game together with players, using real feedback to refine balancing, progression, map generation, co-op and the overall game feel before the full release.”

Approximately how long will this game be in Early Access?

“I currently expect TRUTZBURG to remain in Early Access for approximately 6–12 months. This may change depending on player feedback and the direction of development.”

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

“Throughout Early Access, I plan to expand and refine TRUTZBURG with additional content, progression, maps, enemies, bosses and upgrades, while continuously improving balance, visuals, sound, co-op and overall game feel.
The exact scope of the full version may evolve based on player feedback during Early Access.”

What is the current state of the Early Access version?

“The Early Access version contains the complete core tower defense experience and is fully playable solo or in 2-player online co-op.
Players can defend the Trutzburg across randomized maps, build and upgrade their defenses, fight different slime enemies and bosses, take risks by starting waves early, improve through persistent meta progression and continue into Endless Mode.
The main focus during Early Access will be balancing, additional content, progression and overall polish.”

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

“I currently plan to increase the price when TRUTZBURG leaves Early Access to reflect the additional content and improvements added throughout development.”

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

“Player feedback will be an important part of TRUTZBURG's development. I plan to actively gather feedback through Steam Discussions and community channels, especially regarding balance, progression, map generation, co-op and overall game feel.”

About This Game

HOLD THE LINE. UNLEASH THE CHAOS.

The slime hordes are coming. Your fortress is their only target. Make every step toward it their last.

TRUTZBURG is a roguelite tower defense game where powerful towers, randomized battlefields, and endless possibilities turn every run into a new fight for survival.

BUILD. UPGRADE. DOMINATE.

Build your defenses, strategically place your towers, and upgrade their damage, attack speed, and abilities.

Combine different tower types, create deadly kill zones, and turn a simple defense into a devastating army of destruction.

YOUR TOWERS. COUNTLESS COMBINATIONS.

Cards are at the heart of every run.

Customize your towers with powerful upgrades that change how they fight. Boost attack speed, unleash area damage, improve critical hits, and discover devastating synergies.

Experiment with different combinations and create unique tower builds with every run.

NO TWO BATTLEFIELDS PLAY THE SAME.

Explore six distinct biomes with procedurally generated paths that challenge your strategy.

Enter your own seed or generate a random battlefield. Adapt your tower placement to changing layouts and discover new ways to defend your fortress.

TURN CRYSTALS INTO PERMANENT POWER.

Every run brings opportunities to grow stronger.

Earn Crystals and invest them in permanent upgrades that carry over into future runs. Unlock new improvements, strengthen your defenses, and prepare for even greater challenges.

TWO PLAYERS. ONE FORTRESS.

Defend alone or join forces with a friend in 2-player online co-op.

Build your own towers, develop different strategies, and fight together against relentless enemy waves. Two players, two defenses, one fortress that must survive.

BUILD YOUR ULTIMATE DEFENSE.

Victory is only the beginning.

Face dangerous enemies, challenge powerful bosses, and push beyond victory into Endless Mode, where the waves keep coming and the challenge continues to grow.

Build stronger. Survive longer. See how far your defense can go.

TRUTZBURG MUST HOLD.
