Space Invaders Cheats

This level is the deck of an arcade game. The unique
ship is the Shifter. It will occasionally fly towards the screen
a slightly, dodging your tank fire, then returning to the formation
after a second. This is probably the third most dangerous enemy,
as it fires three to five bullets in a single round. If you can
get around it, it is easy. The Boss is one of the classic aliens
you see in the background. He appears in a large form, then begins
a small barrage of laser blasts, following the movement pattern
of a normal alien. As he takes damage, he gets smaller, returns
to the top of the screen, and gets noticeably faster in its movement.
The laser blasts increase a great deal. If you do not have experience
in firing on quickly moving targets, you will not survive this
encounter. If you defeat this difficult enemy, you will unlock
the "Maniacal" difficulty level. Everything follows
expert mode, but your tank and your rockets move unbelievably
fast. You also will automatically have double shot.
