Outcast - Second Contact

This Achievement can be in the Okasankaar area of the game. Zorkatraz is a rectangular shaped prison island to the south west of the map, press twice to bring up map. It will only be accessible as you progress through the main story Mon quest in the area. You will eventually be assigned to find a gun and ammo for Oru so he can go hunt a Gorgor, one of the ingredient for the ammo is Booyat, one of which is held by Martigar, a prisoner on Zorkatraz.

Once you get this far you can speak to Zidar the south most of the two boatmen in Cyana, the main village in the area, there’s no option to speak to him for travel earlier in game. He will take you to Zorkatraz for a fee, 120 zorkins. I would make sure you have lots of ammo/med kits for the upcoming battle. It really helps not just here but in the game in general if you’ve purchasing/upgradeding your weapons in Talanzaar with weapon traders also.

You will have to swim next to the boat to get near the island, diving when told to by Zidar. Once you reach the island the boat will leave. You can swim up an entry way into the prison proper. There are 3 islands in this area, 1 has steps you can climb. Jump north across the islands, you will be under heavy fire from soldiers, until you reach a small central walk way, from here you have a little cover, I found using upgraded Hawk-Mk8 here you can take out most the soldiers. When you’re done here go north into the water again and go up some steps again so you’re on the outer walkway. Make your way around killing soldiers heading towards the green dot on your map, one soldier an elite in darker close will drop the ‘Zorkatraz cell key’ if you haven’t already got it earlier in the game. Once you kill the last soldier the Achievement will pop.

Theres about 15-20 soldiers in this area.

You can then use the key to open Martigars cell and gain the booyat. Use the horn on south side of Zorkatraz and call the boat to return to Cyana to carry on quest.

I think it’s actually impossible not to kill all soldiers whilst in Zorkatraz, Zidar even says he won’t come back if there’s soldiers, but if you do miss some you can return to Zorkatraz by paying Zidar again and going through the journey out again.

Good luck with Achievement.
