What the developers have to say:

Why Early Access?

“I want development to be an open and community-focused process. Any funds received go directly to further development, and depending on how many people support the game, I can take time off of my day job to accelerate development.”

Approximately how long will this game be in Early Access?

“Barring any unforeseen event, the game will likely be in early access for at least three years. Likely longer.”

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

“The full version will hopefully have many more units, turrets, spell and ugrades, and should be balanced and fun. It should also have a single-player mode with a story and a mix of puzzle- and action-elements.”

What is the current state of the Early Access version?

“This is an early version with a bare minimum of content, but it is playable online. Currently, you need one other person to be able to play.”

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

“I plan to raise the price slightly if or when the game leaves early access.”

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

“The Discord channel serves as a forum where anyone and everyone can make suggestions that will be considered, and I invite everyone to join. I regularly post development updates there.”

About This Game

Castle Siege is a multiplayer 1v1 tower defense and offense game, set in a stylized medieval world.

One player attacks, and the other defends. The attacker can buy units and send them out to destroy the castle. The defender can place turrets along the path to stop the units.

Upgrade your units or turrets to give them special traits like lifesteal, health regeneration or extra damage.

Buy magic spell cards to inflict damage on your opponent, or to buff your own troops.

  • Tactical tower defense gameplay.
  • Strategic tower offense gameplay.
  • Use spell cards to gain an upper hand.
  • Level up by killing units or turrets.
  • Gain stronger spells and upgrades.
  • Customize your castle flag using colors and symbols.
