Exclusively for Sony PSP, the game retells the classic story of two human brothers trapped in bubble-blowing dinosaur bodies by an evil nemesis. The action takes place in two "Towers of Entertainment", a prison comprised of cylindrical sections which form the game's levels. The action revolves around three screens on a central spindle where puzzles must be solved to progress to the next level. Here you will find all the classic elements of Bubble Bobble gameplay - the monsters and the bubbles, but wait, the game's just got tougher! Bubble Bobble Evolution will test your intellect as much as your reactions.
