In the heart of the sleeping city, there lies incredible wealth. The city gates are well guarded, but no one is watching what's under their feet. The dead of night provides just enough cover for you to tunnel your way to untold riches and plunder the city from within. But you must quickly, because a rival thief has the same plan. In Prowler's Passage, you and your rival burrow into the city through a network of underground passages to grab valuable items while attempting to gain control of key districts. Steal the best items, create the longest passages, and control districts to become the premier prowler!
