Metanet has flipped 200 extra levels for N+ onto Xbox Live Marketplace, where people haggle for camels and apples.
The bundle, broken into 150 "easier" single-player levels and 50 "hardcore" co-operative stages, costs 200 Points (GBP 1.70 / EUR 2.40).
We're also told on the Metanet blog to watch out for a "fun surprise" somewhere in amongst all that.
Metanet said earlier this month there had been three bundles - totalling around 750 extra levels - submitted to Microsoft verification at the end of June. Two more still to come, then.
N+ appeared on Live Arcade in March and is well worth your money. You play as a stick-man ninja who flips around the level collecting gold while avoiding deadly traps.
Head over to our N+ review to find out more.
