Liner

Liner is a Special Item from Wario Blast: Featuring Bomberman! that gives the player the ability to place a line of bombs at once. The item is obtained after defeating P-Flower in Round 4. After collecting this item, the player can quickly press twice to place a line of bombs in the direction the player is facing, as long as at least one Extra Bomb has been collected. The length of the line is equal to the number of bombs the player can place at once, and the ability requires at least two tiles of empty space to be used.
