Available for purchase off the XBLA for 800 Microsoft points is Merscom's Buku Sudoku, a puzzle word game featuring over 1,200 puzzles, online multiplayer, co-op and well ... lots of Sudoku puzzles. Over fifteen Sudoku books of puzzles ... or so we're told. The other half of this week's XBLA twofer is Stainless Games' 400 MS point Warlords, a remake of the classic Warlords but in prettified HD and four player Xbox Live support. Though, if you want to be all old-school, they've generously added a pixel-perfect remake of the classic. Browse the screenshots below and ponder an XBLA purchase.
