Check out Bungie.Net and get the details but here's the gist. Play Halo 3 or Halo 3:ODST on Wednesday January 20 and Thursday January 21 while wearing an emblem Bungie has specified and if enough people do it then Bungie Studios will donate $77,000 to the American Red Cross to help the people in Haiti.  Also, if you buy any Bungie Studios SWAG at the Bungie store they will donate all the profits for sales made between now and the end of February 2010 just in case you don't have time to play games on-line but still would like to help.

I am committing to play Halo 3 in a custom lobby after 8PM Central time till whenever on both Wednesday and Thursday. I've got to work the following days but maybe someone else will take the reigns if I gotta go to bed. Anyhow, I'll start a  game in a custom lobby and see where it goes from there. My gamer tag is SENOR HURT (With a space between Senor and Hurt). Look for me Wednesday and Thursday and maybe we'll switch to Matchmaking or Firefight if you need some achievements. Hope to see you then and remember to visit Bungie.Net for the details on the specific way you must set your appearance for them to count you as one of the people playing to donate. 

Hey if this turns out to be a lot of fun maybe we can work this into a regular game night?!
