I just gotten past the part where aliens spawn.Now I'm battling against Greg in multiplayer.
Holy man,you just got owned didn't you,Greg?I just blew away your missiles out of the sky!You are getting own...
WHAT THE? DID YOU JUST BLOW UP ONE OF MY MAIN GUYS?Okay,That's it.
Honestly,you should make it that whenever you lose a level,you can restart it.It could get repetive if you keep playing the same few levels just because you lost one.
