Protect the galaxy from the quasi-mean Commander. Build and upgrade probes to protect your main ship while asteroids and objects fly your way. Use special abilities from the main ship, bounce asteroids off probes or distract them with a decoy. 32 levels of asteroid destruction. 4 types of upgrades per probe (use the tabs on the right after selecting a probe).
-It's a bit slow through NewGrounds for some reason, so I apologize in advance.
