About Castle Constructor

Choose your Blocks, Build your Castle, Save the Kingdom!


Castle constructor is a new take on the tower defense genre. Design your castle how you want it using a modular system of unique, interlocking, inter-working blocks. Stack them up high or spread them out across the map as you try to build the perfect defense.


Landscapes like deserts, mountains, rivers, and hills come with their own advantages and challenges. Fend off waves of enemies who will try to climb over and break through your defenses. From lowly soldiers to powerful siege weapons, you will need to defeat them all as you strive to protect your kingdom.

Game Modes:

  • Campaign - Play through multiple campaign levels to earn resources which can be used to purchase techs and earn new tokens that provide blocks, actions, or upgrades that can be played during a level.
  • Endless Mode - Fight off endless waves of enemies, earning coins and purchasing new blocks and technology as you try to survive as long as possible.
  • Creative Mode - Free play mode. With an infinite number of each card you can build your castle however you want it. Then you can design your own wave of enemies to send against your castle to see how it fares.

Key Features:

  • Modular Castle Building - Build your castle out of multiple different blocks, stacking them up to 5 per tile and taking advantage of both height and adjacency effects.
  • 3d hex maps - Each map is made out of 3d hex tiles with different features like hills, cliffs, rivers, and more.
  • Complex Pathfinding - No fixed paths here. Enemy paths will react as you build up your castle as well as when it is destroyed. Enemies are intent on getting to your keep, going around or even climbing over your walls if it will get them there faster.
  • Projectile Physics - Projectiles are physically simulated and can end up hitting a different target or missing entirely.
  • Techs - Purchase techs in the campaign or during an endless level to improve your towers. Make enemies climb slower, add more defenders to your walls, and more.

I like the simplicity of this game, very good

Fun concept and not very challenging - pretty limited as it is, some level perks/augmentations to add unique challenges to each map would be nice as. Would be nice to see a preview to where the path will move before you place a new tower on it. There is a lot of different maps and a campaign to work through that I think justifies the price tag, but I quickly found the game play repetitive.

Boring game. A strategy of building short towers around the keep and tall towers on the perimeter worked with every campaign map, as well as endless mode where after wave 140 I started "deleting" towers just so I could lose.

As for someone who enjoys TD games, finding this from a content creator was definitely a great find. I was personally able to complete the game in under six hours. Its fun, and quirky in its own way. I would certainly recommend purchasing this and trying the game out if you enjoy TD games. I think the game mechanic of it being a TD game is great. However I do believe it requires additional content to further enhance the game. I do enjoy the difficult start of the campaign, though the difficulty scaling is not there in my opinion. As once you get to a certain point, the games difficulty plummets entirely. I wish the difficulty scaling throughout the campaign was there. I think that personally would've been nice. Maybe bigger maps, more points to defend, even more difficult enemies. As for how the blocks are placed, I do enjoy the restrictions that are in place. I think it limits the player enough that they have to find alternative means of defending the center point. With that being said, I also enjoy how the differences in the blocks currently in the game. How some benefit from certain requirements. This will also require the player to think strategically to …

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
