I have to say, for a game about killing geeks, this has GREAT physics. Berzerk understands that forwards velocity is near constant and gets the calculus behind launches.
NINJA DEFEAT STRATEGY HERE (Does not work on champs): The ninjas just can't be targeted. They can still be hit. The aura temples can hit them if another enemy is in range.
Just to let everyone know: PLASMA FAILS!! I alternate upgrades between Main shot and rang/missle until I have double non-smart missles. Then, just upgrade your shooter to death ray, then missles, then plasma.
I have 4 perfect and 4 gold on amateur, and 3 bronze on pro at the moment. I think they overrated the difficulty of Big Blue. First pro song I did anything right on.
