On my videogame career I have visited many awesome places, like the shadow palace, forest temple, inside of a giant worm, the city of rapture, dark aether, etc.
But I think the coolest place I've ever visited is the living planet PHAAZE. from metroid prime 3 corruption
The atmosphere was incredible, the source of all phaazon and the leviatans that tried to turn other planets into new phaazes, the planet that is alive, the only thing I didn't like is that we couldn't see much of phaaze in the game.
Still it is an incredible place, perfect for one of my most favorite boss battles, dark samus on hypermode difficulty.
Anyway enjoy, this will be the last drawing I'll upload for some time I'll be working on something big...again, so be patient.
Here is the music that plays when you are at phaaze [link]
