This is one of my all time favorite games.
It’s an action RPG, and it was released in the later years of the GBA.
You play as a female bounty hunter, (not Samus Aran) who was tasked with salvaging a research lab. The lab was studying the Scurge, parasite aliens that can take over machines, energy forms, and creatures.
You have a meter showing what your level of infection is. You have to hurry to sick bays before you die.
You can level up, find new weapons, and get new types of energy shots.
This is a really, really good game. I recommend it a lot.
