The producers at Japan Studios have announced an expansion pack to the minimalist yet vexing puzzler Echochrome. PSP users will be getting a 71% increase in levels (yes really) to tackle.Since being released on the Japanese store (in english, bizarrely) people have been defying the laws of physics in guiding oh-so-trusting mannequins to their destination. The pack will arrive on the PSN Oct 9th and you can pick it up for $4.99.
