Boss Fight 8: Sentinel
The Sentinel attacks in a set order: lightly homing purple bullets, a downward-firing center laser, and then invulnerability with squiggly bullets. To avoid the homing bullets, jump as they approach. To avoid the laser, stay off-center. To avoid the squiggly bullets, use the Red Coat's ability to warp or double tap down. The Flamethrower is recommended. Stay off-center to avoid the laser, jump for the homing bullets, and keep firing at its face.
Boss Fight 9: Xedur Hul (optional)
This boss is optional and sparing him grants a Trophy/Achievement. He fires three bullets directly at you rapidly, requiring the Red Coat to dodge. He also drops bombs that explode on contact. Both attacks deal high damage. The Flamethrower and patience are recommended.
Boss Fight 10: Athetos
Athetos summons three Beholder Sentries that fire three shots at a time. Destroying them leads to replacements with stronger attacks (three directions, then a laser). One replacement drops health. To defeat Athetos, destroy the red spot in the center of the ceiling three times. The Flamethrower is recommended to ensure constant damage to the boss.
- Use the Flamethrower to damage enemies through walls in the Mar-Uru area.
- The Red Coat's warp ability is useful for dodging attacks from Sentinel and Xedur Hul.
- If low on health during the Athetos fight, destroy the Beholder Sentries as one drops health.
- The Reverse Slicer is the last weapon in the game.
- Collecting all items, including Health Nodes, Power Node Fragments, and Size Nodes, is necessary for 100% map completion.
