Senran Kagura 2: Deep Crimson - Unboxing
Senran Kagura 2: Deep Crimson is a side-scrolling brawler with busty lasses that makes extensive use of the Nintendo 3DS's 3D capabilities. (Yes, I went intentionally straight-laced in that description.)
TL;DW?
1) A bit lame compared to JP/EU editions.
2) Substantial manual
3) 'Net co-op, and timed DLC (one free if you have SK:Burst)
4) 60 music tracks on the CDs!
