ShirtCity, (I believe) a German e-retailer selling personalized T-shirts, has found an original (?) way of attracting site visitors and trying to convert them into buyers : a wet T-shirt shoot out game.
Aim of the game : shoot different girls in T-shirts with a water gun. The Flash game takes players through different levels. Between levels, the players get rewarded with a video featuring one of the girls in a wet ShirtCity T-shirt. Between level 3 and 4, ShirtCity also offers the players a € 5 coupon, that will be sent to your e-mail when you've finished playing the game.
Terrific mechanic - combining interactive engagement with direct sales ! Let's see who copies it.
