4 players, 4 missiles. The missiles could be combined to a 5th player if you wanted.

The players only had one color and there was a fixed size in pixels. (you could cheat this a bit if you really worked with the display list.)

Edit: as corrected below, each player was (or could be) a different color, but was only allowed one color.

The players could be different colors from each other.
