It's right click shotgun attack has been nerfed severely, I'd recommend focusing on melee and stam to make sure you can gun down everything in sight, because at close range it does not have a reliable melee attack anymore, other than its very weak claw attack. Be careful as a group of Allosaurus can get rid of your newly tamed velo if you aren't careful.
Their ranged attack is bonkers, I went from worrying about every nearby predator, to gunning down everything I don't like.
They burn through Stam fast in turret mode, but they can run forever.
We won't know for certain if their melee damage increases their needle damage until the dev kit releases, or until someone shows conclusive video proof.
Tame one of these and have a blast.
