Final Fantasy VIII uses the Active Time Battle (ATB) system. Each character has an ATB bar that fills over time; once full, they can perform an action. Actions include attacking, using magic, items, or summoning GFs. Pay attention to enemy weaknesses and resistances. Squall's Gunblade has a unique 'trigger' mechanic: press R1/RB as the attack connects for extra damage.

Battle Actions:
- Attack: Standard physical attack.
- Magic: Use Junctioned spells.
- GF: Summon a Guardian Force (takes time, vulnerable to interruption).
- Item: Use restorative or offensive items.
- Defend: Reduce incoming damage.
