The final part of the Modus Operandi trilogy. Brutus and his mutants make their play for the capital wasteland in the last chapter of a war 116 years in the making.

While war rages above, the inhabitants of Vault 101 go about their daily lives unbeknownst to the circumstances of the wasteland. Until they met the most obscure person of Vault 101, life was just peachy for Amata Almodovar and her best friend, Roman Howarth. Will they all walk together or will their lives be thrown into chaos?

Lloyd Freeman is joined by Amata Almodovar as they leave the safety of the halls of Vault 101 in search of his missing father, stepping into the broken world above. Along their grim path, they encounter harsh adversity and new enemies every step of the way, forge new alliances and meet new friends, and through their actions, they come to change the Capital Wasteland forever.
