Why Early Access?

“Mayhem Fortress is outstanding TDS wave defense game where you must defend humanity’s last planet, as a small development studio we aspire to ensure the game is reflective of our gaming passion, we thought early access will give us an opportunity to work with players to receive valuable feedback to maintain/develop and give best experience what players looking for.”

Approximately how long will this game be in Early Access?

“We believe game development is a long journey and since we are at the beginning we face new challenges as we progress. We need to be ensure that Mayhem Fortress is reaching it's goals and we did not consider a specific time frame yet, we believe it won't be more than a year, this may change based on player feedback.”

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

“For early access we have focused on the foundational elements of the game that is required to realise the game’s vision.
The final version of Mayhem Fortress is planned to have a Online/Co-op mode with an expanded gameplay.

What is the current state of the Early Access version?

“For now Early Access includes Survival Mode where handling skills and mech customizations are the keys to surviving endless waves. Earn XP grow your level and build defense towers and set various traps to survive from mech battalions. Survival Mode has been designed to be highly replayable.”

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

“While Early Access is at a lower price to encourage more people to participate in these early stages so that we get the best feedback possible, we anticipate that the game will be priced higher once complete.”

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

Roadmap

About This Game

DEPLOY. DESTROY. RECLAIM.

Mayhem Fortress is a session-based, post-apocalyptic third-person shooter where you pilot heavily armed mechas to reclaim a world overrun by rogue AI and hostile creatures. Drop into dangerous zones, complete high-risk missions, and fight your way through relentless enemies to secure valuable resources and restore control.

Prepare your loadout, enter the battlefield, and survive long enough to extract.

PILOT YOUR MECHA

Step into a powerful combat mecha operated by a human pilot and built for frontline warfare. Customize your machine with devastating weapons like miniguns, flamethrowers, cannons, and heavy rifles, and modify your setup with upgrades and skills that define your playstyle. Use mobility systems like jet-powered dodges to outmaneuver enemies, or engage in brutal close-range combat when things get intense.

SESSION-BASED COMBAT

Each mission is a focused, time-limited deployment where every decision matters. Select your mission, adjust difficulty, and enter hostile territory filled with unpredictable threats. Complete objectives, eliminate enemies, and extract safely to earn experience and resources. Progress through missions, improve your build, and take on greater challenges as you push deeper into dangerous zones.

A WORLD OVERRUN

Fight across a devastated world where abandoned industrial zones, deserts, and wild landscapes have fallen under the control of two dominant threats. The Dominion Protocol, once Helios’ planetary defense force, now operates as a rogue AI-driven mecha faction, enforcing its own cold logic and eliminating all human interference. Opposing them is the Aberrant Swarm, a terrifying mutant species born within Helios’ abandoned bio-facilities, spreading uncontrollably and evolving into increasingly dangerous forms. From coordinated machine assaults to relentless biological swarms and massive armored creatures, each encounter demands adaptation, positioning, and the right loadout to survive.

PROGRESS AND UPGRADE

Earn XP and in-game currency by completing missions and overcoming increasing difficulty levels. Upgrade your mecha, unlock new weapons, and refine your combat strategies. Replay missions to gain experience and master your builds while preparing for more dangerous operations ahead.

GROWING EXPERIENCE

Mayhem Fortress is actively in development, with more content planned including new missions, enemies, environments, and expanded gameplay systems. The battlefield will continue to evolve as we expand the world and deepen the combat experience.
