Iron Conglomerates

Iron Conglomerates are special bricks found in the game. They are indesctructible by most methods, but can be destroyed. They will often block bricks, making the level require clever thinking to pass.

Destruction
While difficult, you can destroy those annoying obstructions. The easiest way is to get a powerup. The J, Q, and O powerups can completely remove the blocks, provided they are in the right spots. A T powerup will transform it into a regular conglomerate, but not remove it. Some missles, such as the Nuke and Hammer missles, will destroy them, but these often have low capacities.
