Xbox Live Arcade's Portal: Still Alive stepped through an inter-spacial tear of savings and popped out the other side $5 cheaper. Valve's fantastic puzzle game, which was also Joystiq's game of the year for 2007, will be 800 ($10) on XBLA this week.

Considering The Orange Box, which includes Portal (minus the 14 "exclusive" levels in Still Alive), is only $20, it may be worth it to splurge on the full package. Especially if you've never played Portal, Half-Life 2 or Team Fortress 2. Also, if you haven't played those games, we hope your decade-long excursion in the Amazon was amazing.
