-= Space Invaders 2600 =-

my personal PSP interpretation of the best Space Invaders version there is: Space Invaders for the Atari 2600

Sequence A1 is the standard space invaders mode: You can have only one shot on screen. Aliens shoot not often, etc.

Every other sequence is a modification to that, it changes the gameplay a little. For each sequence there are
icons displayed to show you what changed. The following basic modification are available, a sequence can mix them:

  Fast Alien Shots = The alien shots fall faster toward the player
  Many Alien Shots = The aliens shoot like crazy
  Invisible Aliens = The aliens are only shown for short period if you hit one
  Weird Alien Shots = The alien shots move left or right while falling
  Doubleshot = You can have two shots on screen at the same time
  Multishot = You can have four shots on screen at the same time

There is one special modification: Time Trial

You have to clear all aliens as fast as possible, if the screen is cleared the game is over. You start score is set to 10000.
To simulate a time trial, the score will constantly decrease. You have unlimited lives, but every lost live will cost
you many points, as you have to wait until your ship is repaired.


Replays
=======

The game can hold one replay in memory.
