The Collector's Edition will cost £19.95, and will include an exclusive in-game item, a poster, a key-ring and trading cards.
Terraria was released last May and quickly became an indie hit. The game was a co-op 2D platformer, but also allowed players to build their own structures, chop wood, farm mushrooms, search for loot and mine for precious metals, while rewarding players for digging deeper and deeper into the increasingly dangerous underworld.
