You might not have played Evolva (PC)

Evolva is a game by the developer Computer Artworks that was released in the year 2000.

Gameplay: Singleplayer, Multiplayer, Third Person, Shooter
What makes Evolva unique is its characterprogression system that allows you to mutate your creatures to fit into the environment the hazards you are facing currently are from.
In Singleplayer you will explore the planet and fight enemies you encounter on your way in classic shoot em up style. Frequently you will get to a point where your current team of creatures cant progress unless you evolve them in a way that helps you with your current problem. There is a huge gap you have to cross, better mutate some gliding ability. Lots of enemies on the way, make your guys more beefy.
The DNA to mutate has to be obtained from creatures you encounter. Thats why the player characters are called Geno-Hunters. They hunt for genomes.
You will be able to have 4 creatures in your team, that you can specialize to do certain jobs and take over the control of one of them at a time to make sure they get it done. The other creatures will be AI controlled and obey certain orders.
The Multiplayer of this game basicaly features a death match between groups of creatures that players nurtured.

You might not have played GIANTS: CITIZEN KABUTO (PC)

Giants is a third person shooter game by Planet Moon Studios released in 2000.

Gameplay: Singleplayer, Multiplayer, Third Person, Shooter, Humor
In Giants the gameplay is heavily affected by the Species you are playing as. There are 3 Species in total.
 Meccaryns - also called Meccs are the technological advanced species. They use heavy weaponry, vehicles and Structures build with the help of Smarties (little inhabitants of the planet). As a Mecc the game feels like a third person shooter.
 Sea Reaper - Using Magic and some structures (again, build with the help of smarties) Sea Reapers can teleport and leap over the battlefield and rush through the water, in which deadly fish wait for the other two species. One Sea Reaper is capable of taking on several Meccs, if he splits them up.
 Kabuto - Think of a mix between Godzilla and King Kong. Now give him sharp teeth and the ability to raise an army of  baby-dinosaurs and you got yourself a Kabuto. A Kabuto is an army of itself and there usualy is only one of them on the planet. But beware - you have a very vulnerable spot on your body that can be exploited by the other species.
The Multiplayer gamemode features an asymetric Team vs Team vs Team environment. The ratio between the species is usualy 3 Meccaryns vs 2 Sea Reapers vs 1 Kabuto or any scaled variant of that. Each species is so well implemented that you will be happy to take any side and people wont fight over playing the Kabuto everytime.
The Singleplayer gamemode features a linear storyline, lots of humors and interesting missions that don't get repetitive.
