UPDATE - I was right, episodes 2-5 are only 200msp each on the 28th. So, considering that episode 1 is FREE, all five episodes can be had for only $10.
I just finished episode 1 last night, and I'm hooked.
Nothing beats FREE people! The Walking Dead, one of the highest rated games of the year, is
FREE from the 25th to the 31st, on XBLA.
Also, on the 28th, the remaining episodes (2 - 5) go on sale. Considering that they're normally $5 a pop, I'm hoping the entire series can be snagged for less that $10.
Enjoy!
