Dragon Ball Z: The Legacy of Goku 2 Missing Namek Locations
Throughout Dragon Ball Z: The Legacy of Goku II there are 7 missing Nameks for players to find. The Namekians are hidden throughout the entire world - each in a different location and collecting all 7 will allow you to travel to and from New Namek from Capsule Corporation in West City.
On New Namek you'll find Cooler (Freiza's brother) and Piccolo's Level 50 Character Gate; which is found in the room just beyond where the Cooler fight takes place. Additionally, right after landing on New Namek you'll be given Grandpa Gohan's Key which'll let you open the shed behind Gohan/Goku's house in East District.
Inside Piccolo's Level 50 Character Gate you'll find a Character Trophy.
Namek #1 - Kami's Lookout (Dende's Lookout)
In the northwestern portion of Kami's Lookout (or Dende's Lookout; whichever of the two you wanna call it -- It'll always be Kami's lookout to me!) you'll find a Namek.
Namek #2 - Tropical Island (4th Island)
On your way to fight Cell with Vegeta (after he absorbs 17) you'll find this missing Namek due east of Vegeta's character gate.
Namek #3 - East District 439 (North of Vegeta Gate)
This Namek is found due west of the Level 35 Goku gate that's found in East District 439. You won't be able to reach this gate until you go through the level 30 Vegeta gate further south. This is much later in the game after Cell becomes Perfect Cell and you're collecting the Dragon Balls.
Namek #4 - Inside Mayor's Residence (Center of West City)
Inside the Mayor's Residence in West City you'll find a Golden Capsule, Namek #4 and the West City Apartments B Access Card which will allow you to reach Namek #5, the very next one on this list.
Namek #5 - West City (Apartments B)
Namek #5 first requires you to acquire the West City Apartments B Access Card which is inside of the Mayor's Residence in the center of West City. If you're unsure where this building is, it's the one that's shown just above in Namek #4s location. The chest that has the Access Card is in the western portion of the Mayor's Residence in a small room.
Once you have the Access Card, you'll want to head over to Apartments B (shown in the map location above) which is where you'll find Namek #5.
Namek #6 - Northern Mountains
Travel northwest from the Save Point in Northern Mountains until you come across the Level 30 Piccolo Gate. Bust it down and continue northwest through this area until you come across the Missing Namek. The easiest time for you to grab this Namek is while collecting the Dragon Balls.
Namek #7 - Northern Highlands
Northwest of where you land you'll come across a Level 30 Goku Gate, you'll be able to see the Namek from this location, but be unable to reach him. What you need to do is destroy the Goku Gate, hit the switch inside which'll extend the bridge that leads to this Namek.
