If you haven't got any cash to donate to charitable organizations who're currently lending a hand with recovery efforts in Haiti, don't fret -- Bungie's organizing a free method for you to show your support. All you have to do is change your Halo 3 (or ODST) emblem to the heart seen in the image above, and play any of the games' online modes this coming Wednesday and Thursday. Bungie's donating a dime for every person who does so to the Red Cross (up to a maximum donation of $77,000). Check out Bungie's blog for more information about the event.
If you're wanting to make a slightly larger contribution, you could also purchase a special version of the Superintendent t-shirt from the Bungie store -- all of the proceeds from which will also go directly to the Red Cross.
