Today Sony announced that select Japanese retailers will be hosting playable demos of the PlayStation 2 game Ape Escape: Million Monkeys from today until July 31. The demo features single-player and split-screen versus modes. Players who complete the single-player mode will be given a secret password that can be used to unlock a hidden costume for Kakeru in the retail version, which will go on sale July 13. The demo is currently available at a number of retailers, including Geo, Toys "R" Us-Japan, and Jusco.
