Gakken LSI Game INVADER 2000
Adobe Illustrator - Vector only
Rules: The tiers were reduced to six and included the missile station, a "barrier", and four invader zones. The points were also changed so that, tier depending, the player could earn 100, 200, or 300 points depending on where he or she hit the invader. Gone was the UFO. The player could only have 1 missile in flight on the board at one time but there were barriers which were destroyed when hit by invader bombs and these barriers would renew once a wave of invaders was destroyed.
