The 3DS maybe a touch tricky to hold for longer sessions, so Nintendo is including a free stand with Kid Icarus: Uprising.
Director and cheerful chap Masahiro Sakurai confirmed earlier this week that the fallen angel's latest adventure will ship with a folding piece of plastic to prop your console onto whilst playing games that may require a more stable base. It'll also help with the precision needed for stylus based aiming, plus support left-handed players when using the Circle Pad Pro.
The accessory has been confirmed for Japan and North America so far, and will likely be available in Europe as well.
