Check surface and underground routes together
Show / hide details
East-side detours are easy to miss just after resurfacing. Check your map before and after elevators.
- Activate the warp and distinguish the east, northeast and south entrances.
- Record the one-key door underground and explore it if you have the key.
- After resurfacing beyond the three-module door, walk around after the battle too.
- Defeat The Emperor, then check the module and pillar beyond.
Nearby rocks and ground markings hint at invisible water paths. Probe the direction where platforms appear instead of blindly dashing far.
Eight eastern modules
Show / hide details
Do not confuse one-key and three-key rooms with doors opened by modules.
| Location | Route | Requirement |
|---|---|---|
| Waterway before the warp | In the underground before reaching the east warp, dash to southwest water platforms. | Detour |
| After plant enemies in the eastern facility | Enter underground east of the warp; after the plant fight, use the north door. | Main route |
| Eastern facility key door | Left of the same facility’s combat room, beyond a one-key door. | 1 key |
| Unmarked southern entrance | Descend the stairs south of the warp and use the inconspicuous left entrance. | Hidden entrance |
| Near the giant’s head | After leaving the southern underground, follow small ledges around the head. Shoot the distant switch to open a downward route. | Ranged shot |
| Surface return fight and three-key door | Beyond the southern three-module door, walk north after the surface fight and defeat the enemies on returning. Check the newly accessible underground three-key door. | 3 keys |
| Beyond the eastern boss | Defeat The Emperor and continue. | Boss defeated |
| Fire platforms in the northeast facility | Enter north/northeast of the warp, reach the fountain platform, pass south through the fire platforms and inspect the small pillar switch. | Chain dashes |
Keys are required in the displayed quantity. Distinguish key doors from module doors by their markings.
Four eastern monoliths
Show / hide details
Paths also hide behind buildings and tents, not just on water platforms.
| Landmark | Search |
|---|---|
| Southern tree | Find the switch near the tree south of the warp and follow the appearing path north. |
| Behind the northern building | At the foot of the large northern stairs, walk behind the building. |
| Right of the boss door | Press the switch behind the tent right of the large boss door. |
| Eight-module door | Open the northeast facility door, fight, take the elevator up and turn left immediately. |
Check around the elevator instead of continuing straight to the next screen after resurfacing.
The Emperor: landings and adds
Show / hide details
Move away from the landing point and attack only during the pause.
- Back away when it leaps; strike a few times after landing, then retreat.
- Clear plants and explosives that block your escape first.
- Keep ammunition so you can still attack when melee is out of reach.
- Return toward the center before being trapped at a wall.
Avoid the landing first, then approach; waiting at the landing point to attack is riskier.
Frequently asked questions
The southern combat room does not open the hidden underground route.
After the first enemies, walk north and return to trigger the additional encounter. Then inspect the three-key door and hidden wall underground.
