Android's in-app billing makes a dent: Dungeon Defenders free on Android Market

Dungeon Defenders: First Wave cost $3 when it first came out. This week, the iOS version will cost you ninety-nine cents. But if you want to play the Unreal Engine-powered tower defense game today, you can have it for free - developer Trendy Entertainment is now leaning on Android's new in-app billing system to pay for the whole thing. We can't give Trendy all the credit, of course, as Glu Mobile's Gun Bros and Tapulous' Tap Tap Revenge 4 are doing the same thing, but to our knowledge both of them were free to play from day one. Free-to-play gaming has been a controversial proposition in the console and PC gaming space - most publishers wouldjust like to sell a game once, and call it a day. On phone, however, where apps are expected to be cheap, it could indeed make more sense to charge users for items and upgrades than to have users "buy" thegame. Either way, we penny-pinchers are pleased as punch with the idea. PR after the break.
