Metroid Prime 3: Corruption Tips

2 more friend credits
1. At the part where you get the Hazard Shield, two assault aerotroopers attack. (This is the only time I've been able to do it) Try to slowly wither away their health until a grapple symbol appears. Grapple it to get the Crash Landing voucher.
2. After you have destroyed the Pirate Homeworld Leviathan, go back to the room of the Pirate Homeworld (more specificly, the mining station) with the Phazon Harvester Drone. Stun it by shooting the weak point, while stunned, use the command visor to command your ship to bomb it. Getting you the Harvester Destroyed Voucher.
