This week's Xbox Live Arcade offering Arkanoid Live! may include a hidden charge that users must pay in order to finish the game.
Microsoft asks for 800 Microsoft Points (GBP 6.80 / EUR 9.60) for Arkanoid Live!, but Xbox.com forum members (as well as Eurogamer readers and posters on the Major Nelson blog) claim this only covers episodes one and two, and that a further 400 MSP (GBP 3.40 / EUR 4.80) is needed to unlock episodes three and four.
The "Full Game - Arkanoid Live!" listing on XBLA only mentions the initial 800 MSP charge.
We've contacted Microsoft to comment.
Arkanoid is based on the old retro game Breakout, where balls bounce off a Pong-style paddle into block patterns above. The DS version was appalling, although we've yet to tackle the XBLA attempt.
