If you don’t know what Left 4 Dead (L4D) or Left 4 Dead 2 (L4D2) is, then please enlighten yourself. You will need the skills within for the zombie apocalypse. Trust.

While I was away on vacation, I was visiting a friend’s cottage and lo’ and behold, I found something rather interesting.

A TANK ALERT box.

Now, most people would attribute this rather curious looking device–colored in Half-Life orange no less–to the toilet it sat beside.
