The combat system fully established — overriding, weak points, the elemental affinities that make each machine encounter a puzzle as much as a fight. Every machine has a weakness is the game's tactical philosophy applied to its larger argument: the systems that appear invincible are not. The civilizations that built the machines had weaknesses. HADES has a weakness. The Eclipse cult has a weakness. Living long enough to find them is what Aloy's particular intelligence is designed for.
