The best possible place, as im sure has been repeated, is the hive, multiple spawn points and also needed for final evo and once you get to 1600 you get devour feast, killer claws are simply the best and your health, weight and damage absorbtion increases. almost nothing can kill you after final evo, and BABIES ARE IMPORTANT having an army to back you up while storming the nests is always a good thing, make sure to make quite a few, ive got five brown and five blue currently, working up for a large attack force. Use devouring feast only to get food back as other corpses are needed to improve your swarm to mature and to heal them after a battle. Only use lethal bite if you absolutely have to, as it drains you of food needed for babies, Only use lighters for fires, as wood is needed later. be sure to stock up on brown alien corpses and blue(mature) alien corpses as you need three per baby of each type, and to heal them. and also use feral rage if something is harming you too badly (which it shouldnt at final evo) as it is very useful and again DEVOURING FEAST simply the most useful skill to have, 150-200 hunger per small blue alien corpse... enough said. make brown aliens as much as possible as they are good defenders of key areas to you, and blue aliens for an attacking force or hunting party, youll need a distraction in areas infested with dire reapers (like east of hive) as they have quite a bit of health and heal from being fed, use this and youll dominate with the alien.
