About this app

Developer Description

America is dead, now fight for its remains. Save Philly — or conquer it.

They say the world ended a hundred years ago, yet it still turns. In the century since, Philly has been torn apart by rabid monsters and rabid men. Highwaymen, slavers, and militias have carved up territories and claims, while simple villages suffer their wars. You are a simple wanderer looking for work. That’s why you’ve come to the Daughters of Liberty. But a simple scouting job is about to take a turn for the strange, sending you into a spiral of mysteries, intrigue, and brutality. Will you stand by the Daughters? Or will you fight to bring the fire of civilization to your home?

Just fantastic

★★

The stat system is poor. There's no clear way to choose your stats, your options are limited and way it affects the skill checks lets everything down. Character creation is minimal, as are choices and the ones you do get seem arbitrary. Also occasional spelling mistakes.

Absolutely atrocious for the amount of money I paid for it to be this short if anyone else is reading this it's a great story but it's just way too short and makes it feel like you were cheated after you pay
