Saturn Bomberman. When the corresponding Switch is blasted, all Spears on the stage that are associated with that Switch will move after a short delay. The Switch may be used to lower or raise the Spears. Players and enemies may pass over lowered Spears, but raised Spears act as Hard Blocks. Players who are standing over a lowered Spear when it raises will take damage, and bombs placed on top of a lowered Spear will detonate when it is raised.
