In one the coolest Easter Eggs I've seen in quite a while, starting a New Game+ of Bastion on Steam allows players to purchase and throw around Gel Canisters that spawn the iconic turrets we all know and love. Steam being the darling for so many indie developers that it is, it's not surprising to see this kind of extra effort go to the platform.
You can buy the must-play indie rpg of the month from Steam for only $14.99.
