Two years after the Helghast assault on Vekta, the ISA are taking the fight to Helghan. Their goal: to capture the Helghast leader, Emperor Visari, and bring the Helghast war machine to a halt. You assume the role of Sev, a battle-hardened veteran and a member of the special forces unit known as the Legion.
For Sev and his squad, the invasion of Helghan is just beginning. Tasked with securing Pyrrhus, the Capital City, they quickly discover that the Helghast are a formidable enemy on their home planet. Not only have they adjusted to the planet's hostile conditions, they have also harnessed a source of power they can now use against the ISA.
Sev and his squad aren't just fighting the enemy forces - their fiercest opponent is the planet itself.
Welcome to Helghan, soldier!
