I don't quite understand this one. I caught all spies and nothing happened. And I think there was a bug as my objective didn't seem to tally with the amount of loot I took off the spies.
The setting and music is nice and I did see a wanted poster for Keanu Reeves and Nicholas Cage which made me chuckle.
The game would need fleshing out and polishing more, and perhaps add a risk system where something bad could happen if you try to capture someone who isn't a spy.
Also I only saw one person walking around who wasn't in his undies, so to me he is definitely a spy :D
