This is by no means breaking news, but if you like killing zombies AND flash-based online video games, then go check out the latest incarnation of Sean Cooper's Boxhead series, Boxhead: The Zombie Wars.
In this version he's added defensive turrets and barricades, which is just about my favorite thing ever, because my style of game play in most strategy games is one which my friends have dubbed "Gun Island." I like building little forts out of video game couch cushions. And by couch cushions I mean mortar and rail gun turrets.
I scored 2.4 billion points today! (It's not as impressive as it sounds...)
Come to think of it... I hate my life.
