Space Invaders Revolution Unlockables (DS)

Taking the form of a world tour, players must battle waves of invaders in locations around the globe, eventually taking in a climactic showdown with the UFO mother ship on the moon. With unique rules for each geographical stage, the player must battle through three rounds to successfully defend that particular location before moving on to the next. In London, for example, players must shoot the invaders in a colour-coded order to defend Big Ben. At the Acropolis, Athens, the challenge comes in the form of a heavily armoured but lone invader, which takes several well-timed direct hits to kill.

Other novel forms of videogaming's archetypal aggressors, such as shadow invaders that blink in and out of invulnerability and giant invaders that must be killed piece-by-piece, bring the total of unique invader types in Space Invaders Revolution's New Era Mode to 13. A classic title like this can surely cause trouble to any die-hard fan of the modern titles, so we offer you a list of unlockables below, which will aid you in your quest:
