The Dark Corps are gathering for the fight of their lives! This special-mission story takes place during the events of
Dark Corps: Winter Watch
and
Dark Corps: Dark Ops
, and shares the incredible undertaking of the scattered Dark Corps teams coming together at the base of Impossible Peak to prepare for their final assault against the Dark. Old friends must rise to new challenges, while familiar villains return for a second crack at the Dark Corps. But coming together at last is only the first step, because a formidable foe waits for them at the base of the mountain, lurking in the shadows... and it will take nearly every member of the Dark Corps if they have a chance to defeat the most powerful Dark they've encountered yet!
