Liner

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