The new battle system that makes FF VII different from previous RPGs involves the Limit Break Command and using Materia. The Limit gauge starts to fill up with each successful attack from an enemy. Once the gauge is full, each character can perform their unique attack (Limit Break). Materia (Mako crystals) are magic orbs packed with ancient skills and knowledge. Special abilities become available to the equipped character. You won't believe what the Summon Monster (called by using random Summon Materia) can do!
