what is the helghast home planet in killzone shadowfall
Killzone Shadow Fall Following the Petrusite detonation that rendered the planet Helghan uninhabitable in Killzone 3 (an event now referred to as "The Terracide"), the ISA grants refuge to the Helghast survivors on the planet Vekta, allowing them to colonize half the planet, with that half of the planet dubbed New Helghan. A massive security fortification called The Wall is constructed to separate the two civilizations from each other, due to the resentment they bear over the previous war. Both the Vektans and Helghast routinely perform covert operations against each other in the hope of finishing the war each claims the other started. The majority of the game takes place in Vekta City, home to the Vektan Security Agency (VSA) headquarters, as well as a prison in New Helghan, and Helghan, the original homeworld of the Helghast, now dead and shattered due to the Petrusite detonation.
