This week's standard games are Flotilla, Atom Zombie Smasher, and Air Forte. As usual, pay at least $1 for Steam keys (as per Steam's rules on giving out keys). If you beat the average, you can get Thirty Flights Of Loving too. All the games (minus Flotilla) include the soundtracks.
The keys this time are separate, not all-in-one like they used to do, so if you already have one of the games you can give those keys to your friends!
