Evolva

This is the Future... Mankind has mastered genetic engineering. Take control of a team of genetically modified warriors called GenoHunters and guide them through awe-inspiring worlds. Genos can adapt to any situation by mutating at will, acquiring new weapons and abilities as desired by absorbing DNA.

You have twelve organic worlds to explore. Weapons include fire breath, giant claws, electrical weapons, gene disruptors, necrocytes and flammable vomit.
