Taming wild animals is a challenging task in Atlas, and if you aren't prepared well, then you can get easily overpowered by them. Some of the most powerful animals in the game are alpha animals, and taming them is not possible due to their strength and weight.
Fortunately, the Tamable Alphas mod allows you to tame alpha animals by reducing their weight.
Currently, only one animal is tamable with this mod, the alpha bear. However, more alphas will be available in the future, so keep your eyes peeled for updates.
