This is a deal called the "humble bundle 2" for 5 indie-developed video games, for the PC, Mac or Linux. There are 5 downloadable games, individually worth $85, but you can pay whatever you want for them.
This is how the deal works - you decide how much you want to pay for these games, and send it to them by paypal. You can choose to send some to charity, some to the game developers, or to the Humble Bundle organisers themselves. They are going to get some people sending $0.01, but I personally am advising you to reach a bit deeper into those dusty wallets, and perhaps think about donating $10...
The games you get are:
- Cortex Command
- Revenge Of The Titans
To be honest, this is an EXCELLENT offer. I've played Braid, Osmos and Machinarium from the above list, and all 3 are excellent little puzzlers. It's DRM free, meaning the games are yours to download and do whatever you wish - there are no restrictions.
I bought the Humble Bundle 1 when it was released way back in May 2010. At that time, I bought it for the World of Goo game, which was totally excellent.
