Black & White 2 is a piece of abandonware, meaning the past copyright holders do not uphold copyright any longer, and as such can be downloaded from websites like My Abandonware.
I found a discord that has a mod that lets me play the game again even Black & White 1 also i can play as the other 3 Tribes from the 2nd game too I will be uploading more soon just stuff has come up atm.
The ol' girl still looks pretty good for nearly 20 years ago. Shame we never got another sequel, some modern machine learning AI for the creature would be wild.
