The idea is the classic Space Invaders with waves of attacking ships. Fight through these hoardes with 5 different types of gun powerups and very powerful rockets.
Get through a set of attack waves and you will duke it out with a tough end boss. The sounds are surprisingly good, and the graphical effects of explosions
Control and fire of the ship is with your mouse.Be sure to use your rockets (right mouse button) often as you have a lot of them and they can clear out enemies fast.
Grab as many powerup icons as possible.
Tips:
Tornado can have up to 5 levels of power-ups.
Each level gives you both more life and a more powerful weapon.
Every time you are hit, you will lose 1 power level.
When all power levels are depleted, your game is over.
When you reach the first end boss, pound him with rockets and you will destroy him in no time.
