Interstellar Attack The theme of Interstellar Attack is totally connected with space, where invaders, spaceships, and asteroids are flying around, making the game so nice. It looks like an arcade game, in which a spaceship on reel 1 shoots at the items located on the rest of the grid. The soundtrack while shots and during the game in general also suit the arcade theme.
Depending on the symbols that land on the grid and spaceships that appear on reel 6, the number of shots will vary as well as the payouts. There are 4 types of spaceships, which can fire 1, 2, or 4 shots. Sometimes, several spaceships can land on reel 1 at once. Invaders of different colours show their value exactly on the gaming field. Each invader can land on determined for this symbol reels only.
