Chapter 1: Battlehammer

This opening section of Metroid Prime Hunters introduces the core gameplay loop of scanning, battling rival hunters, and collecting Octoliths. Unlike other Metroid games, encounters with other hunters and boss fights play a much larger role, and missing scans during these moments can permanently lock you out of certain logbook entries. This guide focuses on helping you progress efficiently while ensuring you don't miss important scans or upgrades.

Make sure to scan enemies and objects as soon as you encounter them, especially during boss fights or hunter encounters, since some scans can be missed permanently. It's also helpful to clear enemies before exploring rooms fully, as this makes it easier to locate hidden upgrades and scan targets without distractions.

Several scans in this section must be obtained during specific encounters and cannot be collected later. Pay close attention to entries marked as SCAN NOW, especially during boss fights and hunter encounters, to avoid missing them permanently.

When fighting hunters like Kanden or Spire, staying mobile is key. Try to keep distance and use strafing to avoid their attacks, while taking advantage of openings to deal damage. Lock-on targeting can help, but positioning is often more important in these encounters.

Many rooms in this section contain hidden paths or upgrades that are easy to miss during initial exploration. Taking time to revisit areas after clearing enemies can help uncover additional resources and ensure you don't overlook important items.

After Samus' ship lands, scan her ship. Directly next to Samus' ship is a console that can be scanned for the Celestial Archives entry. Scan the symbol just above the door to get the Alimbic Prophecy 01 entry. Proceed through the next few doors to enter Helm Room.

As soon as you enter the room, scan the side of the pillar for the Synergy Processor entry. Directly across from the processor is the scan for the Synergy Drive. Use the ramp to go up to the second level where you'll find the scans for the Port Helm and Starboard Helm.

Shoot the 4 conduits in the room to find the key, and use the key to get the artifact. Continue into the next room and enter the portal.

Boss Strategy: Cretaphid

Cretaphid can be difficult if you focus only on attacking directly. Instead, target the red sensors on the totem first to expose its weak point. Staying at a safe distance makes it easier to avoid incoming attacks while dealing consistent damage.

Then scan the blue panel next to the door to get the Biodefense Chamber A entry. Shoot the red sensors on the totem to expose the Cretaphid, then shoot it to deal damage.

Proceed a couple more turns to find the scan for the Magma Vent. Jump up to begin another battle. Go up in the room to get the scan for Spire. Drop back down to the ground level to find the scans for Science Sarcophagus, Battle Sarcophagus, and Alimbic Scripture. Return back up in the room and scan the Blastcap.

After defeating it, obtain the Octolith and begin the evacuation back to Samus' ship. When you get to the Echo Hall, you'll encounter Weavel, who needs to be scanned. After dealing enough damage to him, he'll put down the Halfturret, which also needs to be scanned. After destroying the turret, continue the evacuation to Samus' ship.
