The Chozo may no longer inhabit this planet, but signs of their time here can be found all over its interior. Busted doors slow your path and item tanks increase your Power Suit arsenal, but the security units make the biggest impression. Expect plenty of resistance the deeper into the planet you travel.
Autoad
These spider-like machines have the ability to emit an Aeion disruptor field. This raises the question: if these things were created to disrupt Aeion Abilities, were they made to combat intruders, or other Chozo?
Gunzoo
Gunzoos function more as obstacles than as threats. Their movement is confined to a single laser rail while they persistently fire a laser in their target’s general direction. A Gunzoo can change the trajectory of its laser in one of two directions, depending on the angle of its rail. Overall, they don’t present a great threat and can be easily avoided if you keep moving when you see one.
Wallfire
Part of the Chozo security system, Wallfires are fire-spitting machines shaped in the form of Chozo heads. They’re stationary, but they can take a beating. They spit fireballs or lines of flame in fixed locations and at fixed intervals. They don’t have the ability to target hostiles, but they can certainly slow you down if left alone.
Autrack
The most dangerous of the Chozo security units, the Autrack starts off in a harmless-looking ball, only to pop out and track anything except life-forms native to SR388. If you see an Autrack laser pointing at you, run or hide. A single shot from one of these machines is devastating, and destroying them is no easy feat.
