Missile Strike, I share some but not all,I worked to figure it out.
1.Give up the rt,and lt bases you have to be really good to save the three.
2.For the first 3 rounds be patiant and shoot them down in groups,if you do this when your down to about 2-3 meteors fire your missles in a pattern across the top of the screen where the meteorites first appear.It will start a chain reaction kill meteors and save missles for the next round.
3. At round 4 you have to start firing in patterns at zones along the top and center of the screen.
theres timeing and plcement involved but knowing this much you should be able to figure that out.
Now if someone could tell me the trick to space invaders.
