General Stuart Adams was the ISA General in charge of the Vektan SD weapons platform at the time of the Helghast invasion. He is the main antagonist in Killzone, and in a way, the final boss fight. He was secretly in league with the Helghast and deactivated it so that the Helghast could succeed. His betrayal was unmasked by Jan Templar and his team, who Adams constantly tried to stop. He was confronted on the platform by Templar who mortally wounded him. He was killed when wreckage from the destroying platform fell on top of him. He is also mentioned Killzone: Liberation.
