What the developers have to say:

Why Early Access?

“Idle Monster TD is a fully developed, complete game. However, we are still constantly working on and releasing new content, as well as adjusting the balance and pacing of the game. The developer is incredibly active in the game's Discord channel, where he responds to the community's feedback and often implements their suggestions. Your data/progress will never be erased, including when the game leaves Early Access.”

Approximately how long will this game be in Early Access?

“Idle Monster TD will be in Early Access until we collect enough feedback and have enough content in the game to satisfy the majority of the community and keep them interested in playing for an extended period of time. This could take 2-3 months.”

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

“The full version of the game will be substantially improved compared to the Early Access version. We plan to add more monsters, enemy types, mini-games, events, maps, and multiplayer features that will allow more interaction among players.”

What is the current state of the Early Access version?

“The game is already in a fully developed and complete state. All of the features listed in the "About This Game" section are already implemented. The game and all features are 100% stable - there are no glitches or bugs that prevent you from playing or accessing any portion of the game.”

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

“Idle Monster TD can be downloaded for free. The game gives you the option to purchase things at the in-game store. The price of the items that you can buy at the in-game store will remain the same.”

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

“The community can get involved via the Steam forums, Reddit, or the Discord channel. You can find links to all of these locations in the Settings menu in-game. We listen to your feedback and suggestions and want to include you in the development process and the future direction of this game.”

About This Game

Over 1 million players!

Protect the...monsters? As the commander of the United Monsters Alliance, you’ll defend your homeland from menacing machines in Idle Monster TD.

This delightful take on tower defense flips the script, putting you in charge of helpful creepy-crawlies trying to stop robot invaders from pummeling your base. Strategically place allies like Sea Stallion for extra-speedy attacks, or use Firefly for heavier damage. And if things get real dicey, just wipe the map clean with a firestorm spell!

Eradicating bots gives you upgrades to bolster power, speed, and other stats - and the more bots you obliterate, the more monsters you’ll unlock. Idle Monster TD’s menagerie is filled with awesome beasts, like cute water sprites and scorching fire devils. Discovering new creatures is part of the fun.

Like any loyal pal, Idle Monster TD takes care of itself when you’re away. Come back in a few days to claim gold and power up your defenses. Those robots don’t sleep—but neither do your monsters.

  • Unlock 44 unique monsters of different elements (Water, Air, Earth, and Fire), all of which have different skill sets that make tower synergy crucial to success.
  • Strategize by placing up to 10 monsters at a time. Determining the most effective combination of their elemental skills and passive boosts will keep you entertained and speculating for weeks!
  • Play through 8 different maps, each requiring different strategies to defend most efficiently.
  • Bi-weekly PvP tournaments give this casual game a competitive edge.
  • Discover countless upgrades, research, spells, artifacts, relics, technology, and more to level up with a variety of different resources.
  • Several rewarding mini-games, such as Drone Swarms, Cargo Ships, and Tech Ships.
  • Non-stop, endless gameplay!
  • Fantasy RPG-based world and classes.
  • Complete tons of daily missions and achievements.
  • Offline gold earnings reward you while the game is closed!
  • Fun and cute pixel artwork.

Idle Monster TD is a perfect blend of the Idle and Tower Defense genres. The game is endless and can mostly play itself without you watching. However, an immense amount of strategy is required to play efficiently and place well against your peers on the leaderboards. Go on an epic never-ending quest, explore a fantastic world, battle robots and monsters, and defeat epic bosses in Idle Monster TD!
