Humble Bundle is highlighting another publisher in their latest offering as Rockstar Games partners with them in an effort to raise funds for the Rainforest Alliance.

For those who might be unfamiliar with the name, Humble Bundle is one of the biggest reasons people should invest in PC gaming. Throughout the past few years, they have offered numerous bundles of games at extraordinarily low costs, often lower than how much a full-priced game would be at launch. And a portion of all sales go to charity, so gamers can feel good while they spend money.

This time around, they are doing a special bundle with Rockstar Games in an effort to save the rainforests. For only $15, gamers can get themselves $196 worth of games, all from one of the biggest names in the gaming industry.

So, what exactly is up for grabs? For just $1, players will immediately have access to the infamous "Manhunt," "Grand Theft Auto III," "Grand Theft Auto: Vice City" and "Max Payne" — all classic titles from Rockstar's extensive library.

Following that tier are the rewards for those that beat the average which, at the time of this writing, is at $9.79. Here, players will be rewarded with "Bully," "Grand Theft Auto: San Andreas," "L.A. Noire" and "Max Payne 2: The Fall of Max Payne."

Finally, the $15 tier will give players every downloadable content (DLC) from "L.A. Noire," "Grand Theft Auto IV," "Grand Theft Auto: Episodes from Liberty City" and "Max Payne 3."

Take note that purchasing a higher tier will reward the buyer with all of the lower tiers as well.

A portion of all purchases will go to the Rainforest Alliance, a charity group dedicated to keeping the rainforests of the world alive and creating sustainable communities.

In addition to that, Rockstar is not taking any profit from this deal as they have been willing to give up their entire share to further support the Rainforest Alliance charity.
