Nano Assault Neo review. Classic Game Room presents a CGR Undertow review of Nano Assault Neo on the eShop for the Nintendo Wii U developed and published by Shin'en. If you combined Super Mario Galaxy and Robotron, shrunk the results down to a microscopic size and injected it onto an infected cell, you'd pretty much have Nano Assault Neo. This stunning Wii U shooter adapts the planetoid concept of Super Mario Galaxy to a cellular level. Fight off alien-looking viruses as you fight from cell to cell. This is one of the Wii U's most gorgeous games, a throwback to the time when launch titles for new systems had the ability to stun us with their graphics. Nano Assault Neo does precisely that. This video review features video gameplay footage of Nano Assault Neo on the eShop for the Nintendo Wii U and audio commentary from Classic Game Room's Derek.
