When Sony announced its “Spend $100, Receive $20” PlayStation Network promotion earlier this week, we pondered how it expected gamers to accrue such a sum. Of course, we weren’t privy to the outrageous October release schedule, which has been gradually growing over the past 48 hours.

Joining the likes of Retro City Rampage, The Unfinished Swan, and Joe Danger 2: The Movie, will be Machinarium – a quirky hand-drawn puzzle game developed by Czech studio Amanita Design. The game released on the European PlayStation Store last month, but from 9th October it will be available in North America for $9.99. A Vita version is also apparently in development, but the team has “no idea when it will be released”.
