If you've been avoiding spending 800 Microsoft points in order to let Treasure's beloved shoot-em up Ikaruga kill you repeatedly, then perhaps the Xbox Live Deal of the Week is for you.
Black and white has never been quite as complicated as it is in Ikaruga, the shooter that adds an interesting polarity mechanic to standard gameplay, with black and white bullets only affecting white and black ships respectively. The Dreamcast and Gamecube shooter got a lovely Xbox Live Arcade port last year, and now that port is available to Xbox Live Gold members for half off this week. 400 Microsoft points, or $5 in real money, is a ridiculously low price to pay for the hours of sweet frustration Ikaruga supplies.
Deal of the Week: Ikaruga [Major Nelson]
