Special Cluster

The Islander already has the special gun and he quickly put a hole in Landling's head and it died. 

Screams of agony and disparateness were found everywhere and Elias watched many Islanders being killed and dragged into the water.

Tud, a gun dropped on the sand

"You can kill it with this gun," Elias' neighbour who killed the landling said. But Elias' attention was on the sky and the surrounding area. 

Apart from landling killing Islanders other Islanders were killing other Islanders that was the moment they showed the sign of mutation.

This chaos was the reason numerous Islanders left the Cluster. This part of the Red Base harbours a very high number of Grey Creatures.

Cluster E was the safest location and the most dangerous. It's safest because there will be no fear of stealing or getting killed by another person. The Commanders made sure that any Islander here was free and he would be safe from other humans.
