In front and rear guns, the power of the weapon can be adjusted. There is a plethora of front weapons, including pulse cannons, multi cannons, plasma guns, missile launchers, and more. Rear weapons include side guns, rear missiles, plasma, and fireballs. A neat thing about the rear weapons is that they operate in two modes. Operating weapon in either mode takes the same amount of energy and modes can be changed any time.
Sidekicks are attachements to the left and right side of the ship.
Some sidekicks, such as dual cannons, have unlimited ammo, while others, such as post-it mines and microbombs are in limited supply. Sidekick can be purchased just for one side of the ship or for both sides. A neat thing about sidekicks is that if the ammo is unlimited, they will fire at the same time as the main guns. I've also noticed that when a sidekick is hit, the ship takes no damage. There are also special weapons.
