Ion Assault - the true next-gen shoot-em-up experience

Quadbomb
Intelligent Mine set to prevent trespassing in Solarius territory.
Becomes active once you enter its activation radius.
Only approach carrying enough Ion Particles to fry it before collision!

Solarius Swarmer
Always appear in large numbers that fly in formation.
Only engage once in formation.
Try to neutralize swarm units by wielding some Ion Particles like a shield in front of your ship.
