It's time once again for another 100% Bungie approved and X3F certified Halo 3 Double EXP Weekend! This Double EXP Weekend, we get to celebrate Cinco de Mayo with a new Legendary Map Pack required, ten person, social, free for all, Fiesta gametype playlist called "Cinco de Mayo". How appropriate, right? For those who aren't familiar with Fiesta, it's pretty much Slayer but every time you spawn you're given a random weapon or two. Kinda like a drunken, super violent fiesta ... get it? Also, since it is May, Bungie rolled out all the new Halo 3 playlist changes including the addition of a full-time (and ranked) Team SWAT as well as making Social Slayer a 4v4 playlist. Check out the matchmaking updates, go play Fiesta and celebrate Cinco de Mayo the Bungie way.
