Bloons 2 is out, and it's decidedly more of the same awesome balloon-popping, madness-inducing fun that the original flash game was. About as simple a concept as you can get, but the execution is perfect.
Apparently the first game was played more than one billion times, which sounds about right. All that really needs to be said about Bloons 2 is that you get to directly control bees. BEES!
Don't click here if you are a known procrastinator.
