Screw the giga. This is the most OP creature in the game. Pump all levels into stamina, damage, and health. They will literally kill everything in their path. I also recommend putting them on a quetzal. Boom. You get a legit badass fighter jet with infinite ammo.
Very handy and one of my favourite by far. They're just a walking spiky raptor that has multiple abilities similar to how the Theri does and is just a war machine. To tame you just have to wait until it's stationary in its turret mode, (Where it's face opens up and begins shooting) and begin spinning around it as it is very slow. Or just trap it. Either way, I used shock darts and got it out in 3. Just feed it meat and wait.
Once you take it you'll soon see its ability and power, and as far as suggested upgrades, I'd advise leveling up health, damage and stam most, but be generous to speed as well as it is naturally slow.
The abilities go as follow. (Xbox)
Right Stick (Press) (R3) - Thrash
Spins around lashing tail and head shooting darts in a 360° arc around you quickly.
Left Bumper (Press Once) (LB) - Activate Sentry
Opens his face and slows you in which you can begin to shoot spins extremely fast in an accurate direction. Press again to deactivate.
*IN SENTRY* Right Trigger (Hold) (RT) - Shoot
Once in sentry mode, hold RT and aim in the direction to furiously mow down anything that looks at you the wrong way.
These guys are turrets sent from heaven, they do 20 damage per shot in turret mode, granted they have a very fast fire rate, if your mounting it and you shoot its needles, it will do damage based on its melee damage. These are organic turrets
Breed about 8-10 of these bad boys and you can solo an element node/orbital supply drop fairly easily. Just do not attempt one unless they are 120 or higher. You can do the easiest ones with lower, Like 100-, but do not go over like, medium, and make sure to imprint them all, it helps. (They love cuddles. If they request kibble that you don’t have, Cryo them and throw them out again, they will most likely want a cuddle again.)
