The Windows version has everything bundled.
Linux and other platforms will need to have Python and PyGame installed. Usually they're available from your distribution, e.g. on Ubuntu it should be sufficient to install the 'python-pygame' package.
There's a number of households. Every household has a voice. The game has a number of prerecorded phrases for each voice. There are two kinds of phrases: benign and suspicious. There are two kinds of people: obedient citizens (who use only benign phrases) and terrorists (who use both benign and suspicious phrases). Every household has only one kind of people in it: either terrorists or obedient citizens.
The point of the game is to eavesdrop conversations and send SWAT teams to households. You get points if you capture terrorists. You lose points if you arrest good citizens.
You have 16 listening stations in front of you, each of which is capable of eavesdroping a single household. You can tune in or tune out. You hear all the conversations from listening stations you've turned on simultaneously, which makes the game difficult. There are buttons to send SWAT teams. When you do that, that particular listening station is switched to a new household after a certain time.
