X-Force by Benjamin Percy HC Vol 04

Colossus leads X-Force into the next era — and perhaps to its downfall! No one on the team is prepared for a mission that just might fracture their trust and teamwork for all time. And at last, the brotherly battle brewing for the past four years boils over: It's time for Piotr Rasputin vs. Mikhail Rasputin! Rocked by devastating revelations, the squad must regroup at a remote new base. But if the harsh arctic environment doesn’t do them in, Orchis just might! Then, at long last, X-Force takes their fight straight to Henry McCoy — and he will answer for his crimes! In a last desperate attempt to take down the Beast, X-Force will witness the return of…the Beast?! Wonder Man guest stars as the team confronts Hank with their secret weapon! Brace yourself for the final reckoning!
