The Ion Cannon is a 3x3 weapon room unlocked at level 11. The Ion Cannon is the most powerful weapon in the game, dealing massive amounts of damage in a short period of time. The Ion Cannon requires Ion Cores to fire. These affect the Ion Cannon's damage and are built like Missiles.


In Combat

The Ion Cannon is incredibly powerful by itself, but it can this can be further amplified with the "Ion Rush" Strategy. The strategy involves rushing the Ion Cannon at the start of the game with 2-3 100% Rush Command abilities. With correct timing, a player can deal massive damage in a short period of time. Since the Ion Cannon also takes a massive amount of power, 1-3 Armor blocks are sufficient for protecting it.

When To Use

The Ion Cannon is the bread and butter of level 11 ships. Simply put, there is almost no reason not to use the Ion Cannon. It's the most powerful weapon in the game, allowing for massive damage in short periods of time. The only major drawback is its extraordinary power consumption. However, this can be nullified with further upgrades and AI.


AI for rooms like the Ion Cannon can get rather complicated due to its importance and high power consumption. Due to the lack of available power in the later levels, having power efficient AI in a high power consuming room like the Ion Cannon is important. The below AI command requires all other rooms to have Increase Power By 1 to work. Basically, it soaks up any power lost when the enemy attacks a room but redistributes it every time a friendly room falls below 50% health. Since this will happen quite often, it'll help equally distribute power when it's needed.

None -> Set Cheapest Items
Friendly Room HP < 50% -> Set Power To 1
None -> Increase Power By 1

  • The Ion Cannon is called the Iron Cannon in game files.
  • The Ion Cannon's ship level requirement once displayed 10 instead of 11. This was only a visual bug, and it was patched out the next day.
