Independent German outfit Headup Games announced that it's secured the worldwide publishing and distribution rights for a Collector's Edition of Re-Logic's Terraria, as well as the European rights to Edmund McMillen and Florian Himsl's Binding of Isaac -- bringing both downloadable PC games to retail shops for the first time.

The company will release the Collector's Edition of Terraria, the Minecraft-esque sandbox game presented in sidescrolling 2D with retro-style sprites, in the first quarter of 2012. The retail version of this game will be localized into non-English languages, and will include "various goodies", such as exclusive game content.

As for The Binding of Isaac, the top-down action RPG that just released via Steam a month ago, the indie game will receive a Holy Edition in Europe that will contain "several physical additions to please every fans darkest desire." Given the dark story of the game, these are sure to be disturbing!
