Summary
It was a new world Jynn found herself waking up to, so much had changed within those 20 years of experimentation and imprisonment in that suit. She was thankful to be free of that hell but hesitant to take on the roll she found herself thrusted back into. Commander of XCOM, a mere memory of what it once was.

It was no help that the Elders wanted her back badly. Hunting them down like a pack of wild dogs, undermining their cause at every turn. And then those Chosen, another layer of annoyance XCOM and the Resistance had to deal with. Just how integral was she to Their to their Psionic Network? Was there something more? -

Summary
“Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.”
In our world, XCOM is just a turn-based strategic game where you lead humanity into survival against an overpowering alien force. But when you, the Player, gets the isekai treatment, the last thing you expect is to be transmigrated into the body of an atrophied man that was supposed to represent the Commander. It didn't matter that you had the power of save files and save-scumming on your side. The only thing that matters to ADVENT is your recapture. And the only thing that should matter to you, is surviving, and definitely not harassing your 2IC with your roaming eyes.
