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?

“We are using Early Access to build Monsterion alongside its community. Player feedback will help us improve combat balance, performance, usability, progression, and determine which gameplay features and content should receive the most development attention.”

Approximately how long will this game be in Early Access?

“We currently expect Early Access to last approximately three months. This estimate may change depending on player feedback, technical development, testing, and the scope of improvements we decide to make.”

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

“The full version is planned to be a more polished and expanded version of the current game. We plan to improve server infrastructure, performance, matchmaking, stability, combat balance, user interface, onboarding, and controller support.

We also plan to expand the available content with additional monsters, weapons, abilities, maps, objectives, progression features, customization options, and multiplayer activities. Existing environments and gameplay systems may also be redesigned or refined based on community feedback.

The exact scope may evolve during Early Access as we learn which features and game modes players enjoy most.”

What is the current state of the Early Access version?

“The Early Access version is currently playable and includes the core Monsterion combat experience. Players can enter multiplayer environments, control different characters, use a variety of weapons and abilities, fight other players and monsters, explore the available maps, and interact with the current equipment and shop systems.

The main gameplay systems are functional, but the game is still undergoing active development. Players may encounter visual issues, balancing problems, unfinished interfaces, limited content, performance fluctuations, connection problems, and other minor bugs. Some systems, maps, characters, animations, and progression features are still being improved or expanded.”

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

“We plan to gradually increase the price as significant new content, features, and improvements are added. Any future pricing changes will reflect the expanded scope and development of the game.”

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

“We plan to collect feedback through our Discord community, Steam Discussions, player reports, surveys, and direct gameplay testing. Players will be encouraged to suggest features, monsters, weapons, maps, balance changes, and new game dynamics.

We will use this feedback to identify bugs, prioritize improvements, refine existing systems, and help guide the direction of Monsterion during Early Access.”

About This Game

Many Monsters. One open world. Every fight counts.

Monsterion is an open-world monster MMO. Pick your monster at start, choose well it's yours forever. Level it, gear it, and take it everywhere: into the wilds, into raids, into missions.

EXPLORE A LIVING WORLD

Your home is the monsterion village where there is shops, blacksmith, crafting, quest board, guild hall.

Beyond it, four wild biomes: the Whispering Forest, the Great Swamp, the Ashen Quarry, the Sunken Ruins. Harvest resources, crack open treasure chests, and share it all with up to 25 players in one persistent world.

LOOT. CRAFT. GROW STRONGER.

  • Six rarity tiers, from Common to Mythic; every drop rolls its own stats.

  • Named uniques worth hunting; Bloodthirster, Worldbreaker, Aegis of Ages, The Pale Horse.

  • Socket gems, reforge gear, and craft at the blacksmith to shape your build.

  • Go crit, vampire, tank, speed, or magic-find; then farm better loot, faster.

RAID GIANT MONSTER BOSSES

Hidden giants roam the far wilds. Gather your squad, track one down, and bring it down for the best loot in the game.

PROVE YOUR SKILLS IN DIFFERENT PVP MODES

  • Monster MOBA, classic 5v5 lanes. Lead your monster, push towers, topple the enemy core.

  • Humans vs Monsters, an asymmetric team battle. One side fights as humans, the other as monsters. Different sides, different powers, one arena.

ONE CHARACTER, EVERY MODE

Your gold, your level, your gear, they follow you across the whole game. Everything you earn in the wilds makes you stronger everywhere else.
