"Some 15 years after a global meteor strike wiped out most of mankind, survivors form isolated communities, warring each other for remaining resources. Factories need to be retaken, laboratories rediscovered, storage depots examined for usable items. Our hero, Kate, a battle-hardened 30-something, is the very spearhead of these efforts. For the sake of her community, she visits remote locations, assesses factories for possible production, battles creatures and follows a dangerous chain of events, leading to a discovery that will change her life forever." As for the style of the game, I find it hard to box it into Tactical Shooter. It's much more, incorporating elements of adventure, puzzle and RPG. Also it's not just about war, but also solitary exploration and dialogue-driven story.
