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.
It's about the size of a carno with a machine gun head, can easily take out dinos with its ranged attack. Stamina depletes pretty fast in turret mode, can go long distance running, can't regen when in turret mode (on dino) and seemed to be squishy against other velenasours (didn't have a saddle on). Very fun dino, like really fun.
If you build a 2x2 and have walls 2-tall on all but 1 side and have ramps going up this is trappable.
Lead it in by shooting it and standing behind the trap so it will walk up the ramp and fall in.
Use ramp for cover from its needles as you shoot it.
Unless you chain bola this creature, it can not be trapped. It almost always goes into turret mode and shreds you. Doesn't take too many tranqs, though. Just chase, duck, and hide from its bullets. Kind of difficult tame, but not too bad. Higher level tamed Velanos are very powerful, though! Shreds through dinos!
If you want to fight or knock one out, get up close and hope that it will then opt to use its melee rather than it's spines, as the latter will shred you in a matter of seconds. Trapping it with a bola is also a good method as it will be unable to turn its body to fire at you, but still be wary of it's AOE where it shakes and shoots spines in a small radius around it.
