So there are average rexes. They drop meat, prime meat, hide, and keratin. There are tek rexes. They drop scrap metal, oil, electronics, and element dust. There are alpha rexes. They drop tons of prime, cool loot, and some hide and keratin. So tell me: WHY ARE THERE NO ALPHA TEK REXES THAT DROP POLYMER??? thank you for your time happy hunting

If you ever see one and it sees you here's how you tame and stun it

So there's a glitch in both games where there's a rock glitch

The rock glitch works like this

1st you find a rock

Make sure you can't sprint or walk up the rock

Make sure you can easily jump up and climb the rock

Look for something you want to tame

Get club ( clubs are harder or extreme mode to tame) or tanq ( easy mode) or anything you can use to kill

Find the rex then run up the rock ( PS: this works for any other animal including spinos)

The rex shouldn't be able to run up the rock so you can safely hit him or shoot him also melee is impossible any melee weapon is dangerous and I suggest you don't use them (why: they can still hit you and when they do you get knocked off the rock and have to run) also make sure the rock is big and tall or else they can walk on it

Pt 2 coming at 50 ups

I had to knock out a 135 rex out with a slingshot. On day three. I had used my crossbow, two other bows, and all of my tranq arrows. I had absolutely no choice, but to knock him out with a slingshot. It took many stones and tears. But somewhere around 150 stones wasted, I knocked him down fed him, and he was tamed.

If you are looking for a high lvl then I recommend u to go snow biome it has the highest spawning location of rex there will be chances of a high lvl rex to spawn if it didn't then kill the rexes u dont want to tame and go far from that place wait a few minutes and there will another rex repeat this process untill u got a rex of your desire

THIS IS HOW YOU EASILY BEAT AN APLHA TREX,

Lure alpha trex into the middle of the ocean by carrying a herbivore app in the talons of an Argentavis (I used a Parasaurolophus) then use an aquatic mount like Beelzebufo or megalodon to bite the alpha Rex to death, with the water mounts increased speed underwater it can easily evade trex attacks
