Basic Info[edit | edit source]
The Alpha Rex is a bigger, stronger version of a Rex which rarely spawns towards the inland areas of the island. In addition to their own strength, they also buff the damage and resistance of any nearby wild carnivores. They pose a significant threat to any players who aren't fully prepared to encounter one. Alpha Predators cannot be knocked out. The best way to kill one of these beasts is by using a strong Quetzalcoatlus or Argentavis with points put into Health, Melee Damage, and Stamina. Use Raw Meat to heal them in the battle. You can also use a Giganotosaurus.
Defeating an Alpha Rex grants a large amount of XP and gives all nearby players a Trike Bone Helmet Skin. They also frequently drop recipes, high-quality weapons and armor, and various other items.
Alpha Rexes do not drop normal Raw Meat when harvested. Instead, they give very large quantities of Raw Prime Meat.
Behavior[edit | edit source]
The Alpha Rex is, much like the normal Rex, aggressive to anything around it. They move extremely fast and do large amounts of damage. This makes fleeing from one difficult, so it is not advisable to get into a fight with one unless you're prepared to see the battle through.
They can easily destroy non-metal buildings, so it is not advisable to hide from or fight one from inside your base if it is not built to withstand one.
Appearance[edit | edit source]
The Alpha Rex is about 1.5x the size of a normal Rex with a more limited color palette, but with bright red added (mostly Black/White/Red combinations). They also have a glowing red aura surrounding them, making them easier to differentiate from their normal counterparts.
Color Scheme and Regions
This section displays the Alpha Rex's natural colors and regions. For demonstration, the regions below are colored red over an albino Alpha Rex. The colored squares shown underneath each region's description are the colors that the Alpha Rex will randomly spawn with to provide an overall range of its natural color scheme. Hover your cursor over a color to display its name and ID.
Server admins can use this region information in the Console Command
"cheat SetTargetDinoColor <ColorRegion> <ColorID>".
"cheat SetTargetDinoColor 0 6" would color the Alpha Rex's "body" magenta.
Region 2 is not used
Region 4 is not used

Combat[edit | edit source]
This section describes how to fight against the Alpha Rex.
General[edit | edit source]
The Alpha Rex is one of the most powerful creatures in ARK: Survival Evolved, though not nearly as powerful as the Titanosaur or a wild Giganotosaurus. Should you have a Giganotosaurus, do not ride it while fighting the Alpha Rex, as the Giganotosaurus will become enraged and throw you off, where you will have to escape an enraged Giganotosaurus and an Alpha Rex at the same time. Unless a Giganotosaurus is available to take it down, the player and their tribe members will have to concoct a game plan to take it down. This usually involves flying mounts, masses of tamed animals and cooperation amongst players. When done correctly, the attack on an Alpha Rex can be one of the most thrilling things to do in the game.
Strategy[edit | edit source]
It is completely up to the tribe members or player on how they approach the task of killing an Alpha Rex. Teams have been able to use complicated systems to kill them, while others have gunned them down in a barrage of gunfire. The choice on how to do it is the player's, but you can find some suggestions below.
Lead the Alpha Rex to a large body of water where you have an aquatic mount (preferably a Megalodon) then lead the Alpha Rex into the deeper parts of the water and use the aquatic mount to kill it. If encountered by the shore, lead the Alpha Rex to the open waters with a Wooden Raft (craftable at Level 15) plus one other player to antagonize it. Then ride the waves until it is submerged and thus very slow. With an aquatic mount, the Alpha Rex can be taken down easily. Try to get the Alpha Rex stuck behind a stone and shoot it from a safe distance. Bring a friend in the talons of an Argentavis and have him shoot from a safe distance above the Rex.
In an upfront battle, the only dinosaurs that stand a good chance against an Alpha Rex are the Giganotosaurus or a very damage-oriented, imprint-boosted Tyrannosaurus. If you have a Giganotosaurus (with or without a saddle) and a Spyglass, you can order your Giganotosaurus to attack the Alpha Rex. Several Gigas can slay the alpha in seconds. However, something to keep in mind is that while a Giga has stronger base stats than an Alpha Rex, an Alpha Rex gains much bigger boosts per leveling than a Giga. So be cautious even when fighting with a battle oriented Giga when facing a very high-level Alpha Rex one-on-one as the difference might mean it could close the gap on or even exceed the Giganotosaurus' initial advantage.
Another strategy is to find a large rock, preferably larger than your average Rex, and either take down the Alpha Rex using multiple players wielding Crossbows or place foundations and build a turret or two upon them. Note- Make sure the rock is big enough so that the Alpha Rex can't reach you.
A player with a Argentavis is also able to take down an Alpha Rex when carefully attacking it from behind, but this strategy takes some time, as the Alpha Rex has a sizeable amount of Health.
A second tactic which only works on The Center, involves carrying a small herbivore such as a Dodo, Lystrosaurus, or Phiomia in the claws of an Argentavis and lure the Alpha Rex into a lava stream where it will slowly lose its enormous health pool. When you see its health dropping low, just pull it on to safe ground and finish it off with the Argentavis. This strategy just requires some patience, and you should have an eye out for his injuries so he won't die in the lava, otherwise you will lose all the loot and XP. Also, be careful not to fly too close to the lava, as this would kill you in seconds and you would probably lose your flyer too.
A third, far more dangerous tactic is possible because the Alpha Rex's attack range is, like the Rex, still shorter than the attack range of a Spinosaurus. While not advised, a Spinosaurus can hold off an Alpha Rex by "juggling" it until backup arrives in an emergency. With care, a powerful Spinosaurus can kill a low-level Alpha Rex, though it is not nearly as safe as other methods.
A fourth tactic includes making good use of an armored platform saddle. Tribemates manning siege weaponry such as a Ballista Turret or Minigun Turret, using a high-level Brontosaurus, can stand a good chance against a lone Alpha Rex. Have the driver make good use of the Brontosaurus' reach to juggle the Alpha Rex back while the gunners unload on it. This is not recommended with the Paraceratherium with a platform set up as the Paraceratherium lacks the Brontosaurus' reach to keep the Alpha Rex at bay, and while faster than the Brontosaurus, isn't quick enough to outrun the Alpha Rex to kite it.
You can also use a high level Pteranodon (wild Level 140-150) with its roll (C). For example, a level 10 Alpha Rex takes about 7 minutes with a Pteranodon with 45 level-ups in damage. It is advised to look for a high position to regenerate Stamina and kill all dinosaurs in the Alpha's range to avoid its fast health regeneration.
Another tactic is using a strong Woolly Rhino's charge. A strong charge may be able to kill one in 1-4 attacks.
Another easy strategy is to use a pack of Allosaurus. Let the alpha Allosaurus use it's gore attack to slow the Alpha Rex down so it can be continuously attacked before reaching your tames.
Weaponry[edit | edit source]
Use mounts, or ranged weapons. Any physical confrontation is almost always certain death.
Dangers[edit | edit source]
- Do NOT fight the Alpha Rex if you are not well prepared! It will kill you and your whole Tribe within seconds.
- The Alpha Rex is very fast and has a large amount of damage.
- The Alpha Rex is able to destroy any non-metal structures.
- The footsteps of the Alpha Rex can kill you even if Dino Damage is turned off.
Weakness[edit | edit source]
- It's one of the most powerful creatures on land, but in the water it's pretty slow, making it more vulnerable to fast water-mounts.
- Around 20 Spear Bolts shot with a Ballista Turret (aim for the head) will do the trick for a level one Alpha Rex, higher levels may need a substantial amount more.
Notes[edit | edit source]
- Released in patch 193.0
- Other Alphas include the Alpha Raptor, the Alpha Carnotaurus, Alpha Mosasaurus and the Alpha Tusoteuthis.
- Becomes a Skeletal Rex during ARK: Fear Evolved.
- The damage and resistance buff that it gives to nearby carnivores can be seen as an arrow pointing up, with a "+" sign inside of the arrow.
- Force taming using console commands may result in a game crash. This may have been fixed, as the game does not seem to crash in 279.22.
