Xenos, they ARE good, from what I heard from members of the board by their findings.
Ok, to me, Xenos are a great Living Weapon. They can Multiply by using their enemies as host for the hatchlings. They are stealthy creatures, that is IF the environment suits them, like camoflage. When something inflics a terrible wound to them, their acidic blood will melt away object in which in lands on.
So yeah, Xenos are GREAT.
P.S. Want me to go into real detail? o_o;
