All our lives, the only thing we humans have known is war.
War for power,
war for wealth,
and war for glory.
But now, we’re fighting a war to survive.

To the left, right, and centre, we are being assaulted on all fronts from the Alien Covenant Empire, and from behind us, we’re fighting civil wars as our planetary colonies fall into anarchy.
Amongst this chaos, a special operative group known as the Vanguard are working on all fronts, both on the frontline against the ACE, and to prevent the conflicting colonies from destroying each other.
Our story takes place in 2551, the Vanguard’s headquarters are under siege, and amid the attack is a newly appointed Staff Sargent, a young human, named Sunset Shimmer. While identifying as human, she wasn’t always this way, which she is very quickly discovering as her past is catching up to her. Now she must fight with what she once knew, while serving amongst her unit during the most gruesome conflict humanity has ever seen…
