In alpha phase, you must clearly use level rex type dino over 350 with full tek pick up the keys and if you are not solo, be several in tek tier to fight it, you will have a great chance to win if you organize well.

You can solo it,bring 19 rexes and a yuty. Rex 50-60k health and 800 meele should work. Bring more armor sets, a good weapon and med brews. Should work fine
