I did the Alpha king titan fight and here's what I did in both ASE and ASA, In ASE all I did was tame the titans and tame/breed 500, lvl 150 Giga's, that did the job within under an hour, in ASE which was more recent, I tamed a dreadnoughtus, about 50 Carcarahdontosaurs, 4 mechs (for the Mega Mech), and the titans and that was more difficult but still do-able but it's more difficult.
