Last Tuesday, the infamous Humble Bundle stepped forward with what they’re calling their “biggest blast of bundle yet,” the Humble Bundle 4.

If you’re unfamiliar with the project, the Humble Bundle is a way for indie game developers and gamers alike to give back while enjoying some quality entertainment. Every so often, the Humble Bundle partners with indie game developers to include their games in the bundle. Consumers are then given the chance to pay for these games and the option to send some of the money to charity.

The catch, which makes the Humble Bundle what it has become, is the ability to name your price. Any price from $0.01 and higher is acceptable, and will grant you access to numerous games from reputable developers.

This time, the Humble Bundle 4 presents some big-name games, including:

• Super Meat Boy
• Jamestown
• Shank
• Bit.Trip Runner
• Night Sky HD

In true Humble Bundle tradition, there are also bonus games for those who donate at or above the average price. This time, these games are:

• Cave Story+
• Gratuitous Space Battles

A few days after releasing the bundle, the minds behind the program offered an added bonus to anyone who purchases the bundle. When purchasing the bundle, any games you buy also come with a complete downloadable soundtrack, something that might be a rare find in any other case.

Including the games included for beating the average, these games total would cost consumers roughly $100 at normal price. As one might expect, the average price is typically nowhere near this. As of Saturday night, the average was only $5.33.

While some people may not donate a lot, there are certainly those who go above and beyond the call of duty. In the past, infamous Minecraft creator, Notch, was known to donate several hundreds or thousands of dollars to the program. In more recent times, however, an organization known as the Humble Brony has worked to raise money for the project. As of Saturday night, they had donated $5,250, adding a few thousand since the beginning of this Bundle.

When making their purchase, consumers are given the opportunity to decide where their money is going. The split is between the developers, the charities, and the Humble Bundle itself for maintenance costs.

What is unique about this bundle is the sudden change in charities. As always, Child’s Play is one of the recipients. This program reaches out to children who are hospitalized and attempts to lessen the pain and stress associated with hospitalization through video games and other forms of entertainment. A new face this time is the American Red Cross foundation, which works to aid victims of disasters. In previous bundles, donations went to the Electronic Frontier Foundation (EFF), which works to protect fundamental rights regardless of technology.

The previous numbered bundle, The Humble Bundle 3, managed to sell 372,399 bundles and raised $2,169,341.93. Four days in, the Humble Bundle 4 has sold 294,885 bundles and raised $1,572,787.26. Will this bundle truly be their “biggest blast of a bundle yet?”

12/20/11 Update: The Humble Bundle announced today that they would be adding more games for those who donated above the average price. These games make up the former Humble Bundle 3, and consist of the following:

• Crayon Physics Deluxe
• Cogs
• VVVVVV
• Hammerfight
• And Yet It Moves

These games will be available on the special pages designated for each person who donates above the average. If you have donated before now, these games will still be available, along with their soundtracks.
