Hint: Multiple switchyas:
Go the to the lake next to Silva's location with at least one Switchya in the inventory. From the east side of the lake, go towards the fountain and shoot a Switchya towards the plume of the fountain. It should rebound back without being used and increase the total number of Switchyas available by one.

Hint: Quick start:
When first starting, find a DOAsys spire. Once there, rest, then go out and save the game in one of the nearby blue spires . To increase power, crash Goners and Huffman them. The Goners are color-coded: yellow increases Defense more than others, red Offense, green Agility, and gray all three equally.

At first, only go for short forays outside the DOAsys. Go out, Huffman a few Rithms, and return. Once your character powerful enough, travel farther and explore.

The next priority is to get power-ups. The two most useful power-ups in the game are the Boomerang and Nukeya. Only fire the Boomerang when it is locked on a Rithm, since its shots can deplete the Offense level rather quickly. Pick a target at a distance, then let go several boomerang shots after it is locked.

Hint: Stopping quickly:
Press RS + LS for a quick stop.

Hint: Sidestepping:
Sidestepping is useful only to evade shots, and not as a movement option. Your character will not actually sidestep until you release LS or RS (one push is one step left or right).

Hint: Finding crashed Rithms:
If your TV is stereo/surround, listen to sound effects in 3D. This is especially useful when looking for a nearby crashed Rithm to Huffman, or for exploding enemy fire to determine where they are coming from.

If a crashed Rithm can not be seen no matter how much your character turns, step back. It was probably right beside your character.

Hint: Finding spires:
Look at the sky. The spires go all the way up and can be seen at a distance.

Hint: Rithm strategies:
Do not try to lock on to Picassos. Weapons will lose their lock when they turn edge-on . Just follow them at a medium pace, leading your character's shots (that is, fire at where the Picasso will be when the shot gets there).

If there is a Tork around, there will probably be others.

Venuses always travel in pairs.

Hint: Defeating Bosses:
Do not kill Chance until all the lower bosses have been killed. Most of the bosses can be killed with Nukeya, or by standing in the healing spire and blasting away at them.

Save game bug:
Occasionally, a saved game can become corrupted and cause the game to freeze. One way to avoid this is to use all the save game slots available. If this problem develops, go back to an earlier save and continue.
