The Vektan Security Agency is the intelligence branch of the Interplanetary Strategic Alliance and is a major faction in Killzone Shadow Fall. While the VSA is a protagonist faction in the game, it is under the corrupt authority of Thomas Sinclair and is the final antagonist faction at the end of Shadow Fall.


The VSA was established when the surviving Helghasts began to colonize eastern Vekta and established New Helghan as the end of the Second Extrasolar War. The VSA was eventually put under the control of Thomas Sinclair as the organization's Director, but he was corrupt, xenophobic, and wanted to wage war against the remaining Helghasts. Over the next few years, the VSA would become more active as tensions between the Vektans and the Helghasts began to grow and get worse and worse over time.

Events of Shadow Fall

VSA operatives were stationed all over Vekta and Sinclair had campainged for war against the Helghasts. The VSA becomes an antagonist faction at the end of the game after Maya Visari breaks into Vektan Territory and assassinates Sinclair to avenge Lucas who was branded a traitor and killed and to prevent a war between thee tow sides. War was prevented after Sinclair was killed however, it is unknown what happened afterwards but it is assumed that the VSA got a new Director and was less corrupt leaidng to the organization's redeemtion.
