Why did they use lightning? The original suggested lasers or missiles as defense weapons. Something based on the reality of a Star-Wars-type defense against missile attacks. This remake uses lightning bolts? C'mon... that's retarded.

Heh it is pretty stupid.  I don't like the fact that one the first 10 waves from when the waves start you have time to go to school come back and maybe just maybe the missiles have got 1/984.3943 nanometers down your screen.

I wanted to get the full version but the lighting killed it for me.
