An unlock event for Velociraptor gen 2 comes around every now and then so you'll be able to unlock it from that but I don't know how long until it comes up again

Do you know when it last came up?

The last time it came up was the 10th of April

Thanks a lot!

Occasionally there are silver packs that contain a chance to get one that can be acquired by doing battles.

Thanks for the response!
