This wave can be a little tricky, make sure you stay in areas that you can safely dodge the bombs from the red peppers.
Like this...
Wave 92
Position yourself right about here and shoot like crazy! The bombs
from the ship on the right will miss you.
When this guy shoots, you can hide out between the bombs.
Then get back over here and finish him off before the other one gets
close enough to bomb you. If you haven't killed him by then, blast the
other one until he moves into your range, it shouldn't take too much to
finish him off by then.
Wave 93
Keep your head down and keep shooting, watch for safe zones, and get
those power-ups.
Wave 94
Same strategy as the last wave...
Wave 95
Clear the birds and stuff before going for the bear and red pepper.
Now it's easy!
