Walkthrough
- 1Access Requirements:
- Skip the Booster v0.8 (you will receive Booster v2.0 later).
- 2Obtain the Tow Rope in the Core to bring Curly with you.
- 3In the Waterway, enter the Waterway Cabin, drain water from Curly, pick her up, and proceed through the rest of the Waterway.
- 4Find Curly in the lower-right part of the Plantation with her memories gone.
- 5Return to the Graveyard in Mimiga Village and defeat the boss to acquire the Ma Pignon.
- 6Go back to Curly and feed her the Ma Pignon. She will regain her memories and give you the Iron Bond.
- 7Entering Sacred Ground: With the above requirements met, the door to the Prefab House will be open during the final escape sequence. This leads to Sacred Ground.
- 8Prefab House:
- There is a save point here. Save your progress if you are at full health.
- 9The bed cannot be used for resting.
- 10Inspect the bookshelf to be asked if you want to "turn back time". Select "yes" to be transported back to Balcony, outside the Throne Room entrance, allowing you to see the normal ending while preserving your save in the Prefab House.
- 11A hole in the floor is the entrance to the secret stage, Sacred Ground. Jump down.
- 12Sacred Ground B1:
- Upon entering, the Nikumaru Counter activates, tracking your completion time for the bonus stage.
- 13All your weapons will be dropped to level 1.
- 14Head right of the entrance and drop down a secret passageway to a sign that reads, "Welcome to hell!". Make your way back up.
- 15Head left. Below is a staircase covered with death spikes. Jump down and hold Left, using two short boosts to avoid the spikes.
- 16At the end of the staircase, there are more spikes at the bottom. Boost right between the spikes, then boost up to safety.
- 17To regain boost if needed, land on smaller spikes that deal -10 damage.
- 18After landing on the platform, a mysterious voice will speak about Jenka's brother, Ballos.
- 19Head right from the platform, avoid spikes, and drop down.
- 20Collect two weapon energy capsules to upgrade your Missile Launcher.
- 21Proceed across a long floor of death spikes. Conserve some boost for the upcoming shaft.
- 22Inside the shaft, collect four more energy capsules by shooting them as you pass.
- 23At the bottom of the shaft is another row of death spikes. The only safe platform is in an alcove with a Life Capsule. Use your conserved boost to reach this alcove.
- 24Collect the final Life Capsule, which should bring your maximum health to 55.
- 25Jump down from the alcove and boost right to a door. Curly will be unconscious.
- 26Take Curly with the Tow Rope and head to the door. The mysterious voice will speak again about Ballos's past.
- 27Enter the door with Curly in tow.
Items Found:
- Life Capsule x1 (Prefab House)
- Missile Expansion x1 (Prefab House)
- Weapon Energy Capsules x6 (Sacred Ground B1)
- Life Capsule x1 (Sacred Ground B1)
Tips
- Use the Booster as much as possible throughout Sacred Ground, as boosting is faster than walking.
- Conserve a small amount of boost before the shaft in Sacred Ground B1 to reach the alcove with the Life Capsule.
- If you struggle with the spike sections, landing on smaller spikes that deal -10 damage can help regain boost.
