If you haven't already been point-and-clicking away at Amanita Design's gorgeous adventure game Machinarium over the past few months since its digital release, you're gonna have even less of a chance to avoid it when it hits retail (in a box!) on March 5. Lace Mamba Global announced the re-release this morning, noting that the retail version comes packed with some extra bonuses -- a 54-page "concept art document" (seen below), a poster, a printed walkthrough and the game's soundtrack (standalone disc). If you needed any more reason to grab the $20 title, we have to imagine this bag full of goodies certainly can't hurt. Gallery: Machinarium (Retail release goodies)
