Rare plans to beef up Banjo-Kazooie: Nuts & Bolts on 7th April with the Lord of Games' Lost Challenges pack.
It will cost 400 Microsoft Points (GBP 3.40 / EUR 4.80), and adds a series of 12 tests for the bear and bird to build their way through. Succeed and another version of Klungo's arcade game will be offered as a reward.
There's also seven extra multiplayer modes - although they're not detailed - and 250 Gamerpoints up for grabs.
Banjo-Kazooie: Nuts & Bolts was released exclusively for Xbox 360 late last year, but rang rather hollow despite some lovely touches.
