Do as much damage as you can right off the bat, then, on this level, you can go after the slower moving ones while still imposing damage on the faster moving ones up top.
I saved the power-up for last, since there are no extra points unless
you get the power-up before killing any aliens in the wave, it gives you
more time to get ready for the next wave. In this case, I accidentally
hit the power-up too soon, there are going to be bombs from this wave left
over when the next wave hits.The "X" indicates the only place that I can
safely go. There are a couple of other choices, but that's the only surefire
one. I can only hope that the next wave doesn't bomb that spot and leave
me to lose a life.
Wave 7
Not rocket science, just shoot...Lots!
Wave 8
Now that I got through those bombs, I'll get as many of the easy ones
as I can get first.
Then I'll kill this one...
Then I'll get that one and, oh, bonus, I get the power-up at the same
time without changing positions.
Wave 9
I guess I got the easy ones already with the shots left over from the
last wave... Now these fast moving ones should go... Note the positioning
of my ship, the inverted Pacman with a hat is going to drop right into
my trap. If you can, start this wave just to the right of center, and you'll
get this guy first.
Wave 10
Start wave 10 in approximately this spot, and you can get the Pacman,
the flying beer bottle, and anything else that's around.
Looks like a bunch of the green ones got in my way... Look out for
the incoming shots though. Take out as many as you can while staying out
of harm's way, if the Pacmen were to shoot now, I have plenty of space
to the left after those 2 bombs go by.
Whoops!... Exit stage right! But, the rest is easy from here...
