The Scatter Cannon is a Tier 1 Side upgrade, meaning it can be selected as the first Side upgrade, along with the Side Cannons and Side Rows. It is the only Side upgrade to not have something upgrading from it that is of the same name. When this upgrade is selected, it changes the two Side Cannons to two Scatter Cannons, which instead of shooting one big bullet each, shoot three small bullets each, which do less damage per bullet, but overall do more damage per shot. It upgrades to the Grape Cannon.
- Getting scatter cannons will save your turn speed, unlike regular side cannons; they do not make your ship longer.
- It is best to use with other weapons that have multi-directional fire, like the quad cannon. This way, you have a maximum chance of hitting your target.
