S.A.I.F.T.U - I & II (Space Alien Invaders from the Underworld - Atari 2600 game series)

Welcome to SAIFTU: Space Alien Invaders from the Underworld!

They've arrived! The invading forces of Veltareum have set their sights on your planet, and only you can stop them! Jump in your laser hovercraft, stand your ground, and fight for survival as hostile aliens move through the skies. Shoot fast, shoot accurately, and blast the invaders back to the underworld once and for all!

Part 1:

The mission is simple: shoot enemy aliens and rack up points. Reach 250 points to win the game (do this in all Part 1 versions, except for the Points Accumulation one). But stay on high alert... the enemy has deployed a deadly bouncing fireball that can appear without warning during the heat of battle. Dodge its unpredictable attacks while continuing your mission to save the planet. One hit from it, and your entire civilization is immediately over!

Part 2:

In Part 2, the enemy is advancing and their alien mothership is attempting to land on your planet! Your target is the mothership's underbelly, represented by the grey square at the top of the screen above the enemy formation.

The alien fighters will do everything they can to protect their command ship, but don't let them distract you - your lasers won't penetrate them this time! Instead, focus all your firepower on the mothership itself (each version of Part 2 requires a different number of points to destroy the mothership and secure victory). Beware, the deathly fireball will also make an appearance in this one!

Aim true, hold your nerve, and save your world from total invasion!

PS - To truly reset the entire game, for both part 1 & 2, you have to do a HARD Reset on your emulator and console.
