The guys over at TrueAchievements are playing Halo this weekend. "Big whoop," I'll bet you're saying, "So am I." Yeah, but the altruists at TA are playing Halo non-stop, to raise money for Child's Play, a combination of altruism and laziness I fully endorse.
On July 2nd at 8:00 AM EDT, eight TrueAchievements staff members will be playing the campaigns of Halo 3, Halo 3: ODST, and Halo: Reach in four-player Co-Op on Legendary difficulty and will not be stopping for 24 straight hours. That's a whole Halo-day, people.
As donation milestones are passed, the teams will back out to the main menu, add a difficulty skull and resume their play-through with the new skull challenges implemented. As more money is donated, more skulls will be added and more "fun" will be inflicted on the teams.
"At TrueAchievements, we realize that times are tough, and money is tight, but every dollar donated will go straight to Child's Play who works to buy games for children in hospitals... children who, more than any of us, need the positive experience that playing a video game can bring. So, please, if you can, give generously."
Because this is the internet, you can follow along in real time.
