Last week I finally bought an XBox 360...
It was the first game system I'd bought since I got a Playstation (the first Playstation unit, so I'm dating myself a bit there), and after catching my breath from the purchase price, got it home and hooked up to play with. After trying my brother's XBox out, the first game I bought was Left 4 Dead 2.
For those that don't know, L4D 2 (short name) is basically the story of four peoople fighting their way to the safe zone in the middle of the zombie apocalypse. You can play any of the four characters, and if you've got friends with XBox units, can play together online to fight off the hordes of infected and reach safety.
This game rocks! I started playing and didn't even notice four hours had gone by! And killing zombies is not only fun, but pretty relaxing and stress relieving. I've only begun to have fun with this thing, but can't wait to get a copy of Forza 3 to try out, my other gearhead buddies tell me it's fantasic.
