Now, it's time for another deal. Here is the...
Humble Indie Bundle 2

The famous time-manipulating puzzle platformer about a hero and a princess.
Or domestic violence. Or the atom bomb. Or something like that. You have to
play to the end to get it. Maybe.

Control the deadliest war machines in this tactical action platformer
with old school sprite graphics.

A brain-melting, hand-drawn, classic style point-and-click adventure
in a world of living robots.

A puzzle game that's all about biology. Phagocytate the other cells
before they phagocytate you!

A cartoonesque real time war strategy game. The invasion forces
have arrived, and the planet's counterattack relies on you!
But wait, what's your operating system? All of them?!

No problem! All those games are available for Windows, Macintosh, and Linux.
And, just like the last time, you choose how much you will pay. But don't be too tight-fisted, will ya? Gotta keep talented indie developers afloat. Indies are usually the guys who innovate and try different things. Do you want every game to be a MOH or a Madden? No, of course you don't.
Besides, you may have noticed the "help charity" bit in this thread's title. Here's the thing: once again, part of the money goes to the Electronic Frontier Foundation, a civil liberties group fighting internet censorship, and Child's Play, who sends games and toys to seriously ill children in hospitals. So not only you get games, you do your boy scout good deed of the day at the same time.
So, pay up, you stingy sonovabiches! This deal is definitely worth a few bucks! Check it HERE.
