The game uses a top-down or isometric perspective for exploration, with occasional first-person and cinematic sequences. Players travel through towns, wilderness areas, dungeons, and story locations while solving environmental puzzles and advancing the narrative.

Combat is turn-based. Human characters spend attack points on button-based martial-arts sequences, while Gears use fuel and special attacks. The party gains experience, equipment, abilities, and improved Gear performance as the story progresses. There is a primarily single-player campaign with no multiplayer mode.

Explore towns thoroughly for equipment, items, and optional conversations before major story events. Keep both human characters and Gears equipped, since Gear battles use separate weapons, armor, fuel, and upgrade considerations.

In human combat, vary attack strings to manage attack points and learn which combinations produce stronger deathblows. In Gear battles, monitor fuel and use strong attacks selectively; Ether abilities and party support skills are especially valuable against bosses.

Save often, particularly before major dungeon sequences and disc transitions. Some story areas restrict later exploration, so complete optional activities and purchase useful supplies when the game allows it.
