You have to go to skytown on elysia and defeat Ghor to get the plasma beam.
The best beam is the annihilator beam because it does the most damage in metroid prime 2.
The Phazon Beam can only be used while fight the Metroid Prime's 2nd form.
probably metroid prime corruption for wii, but mertoid prime and metroid prime 2 on the gamecube are the cheapest and are pretty much the same Kanden has to say: they ruined metroid orime 1 because they didn't add screw attack. ALSO they ruined Metroid Prime 2 because of beam ammo limits. out of the metroid primes i choose............Metroid Prime 3 Corruption as the best of metroid primes. but if it is an old metroid like Super Nintendo's "glory days" i choose super metroid. i also love metroid zero-mision and fusion.
To beat metroid prime, you must see the color it has. Every color its using is a different weakness. Yellow= Power beam Purple= Wave beam Red= Plasma beam White= Ice beam
Kill Ghor.
the final boss in metroid prime is (kinda obvious) metroid prime. BUT! once you kill metroid prime, you have to fight his soul. I believe the only way to harm metroid primes soul is with the phazon beam. He is very hard to beat if you're not an experienced player.
All you have to do is defeate the Shegoth In the ELDER CHAPEL
Power Beam: From the beginning of the game. Charge Beam: From the beginning of the game. Hyper Beam: Obtained after being attacked by Dark Samus on Planet Norion's control tower. Only usable in Hypermode. Plasma Beam: Obtained after defeating the Bounty Hunter Ghor on Skytown, Elysia. Nova Beam: Obtained after beating the mini-boss Mining Cannon on Pirate Homeworld.
the dark beam is in a storage room in the desert
Ypu have to defeat the grapple beam boss found on dark torvus bog.
well there are two metroid games that use this powerful arm cannon upgrade and that is metroid prime in the end of the game and metroid prime 3 where all you have to do is press the + button on the wii remote to activate along with othe phazon laced weaponry
