Line Attack Heroes is a WiiWare game by Grezzo Games and Nintendo. The game, a project by Mana series creator Koichi Ishii, is a beat-em-up title. The player's goal in the game is to go through the multiple stages and find the pieces of a crystal that was shattered by a malevolent foe. In the game the player will find enemies that will give them their powers once they're defeated.
Line Attack Heroes was announced at E3 2009 as a Wii retail game. After being removed from Nintendo's game list, many assumed that it was canceled. In July of 2010, Nintendo announced that the project had gone through a transition stage and re-announced it as a downloadable WiiWare game a week before its release in Japan.
