On Halo Waypoint there is a look into the new update "Infinity's Armor". In this next free expansion there will be (besides the basic maps, armor, weapon skins etc) will be a file browser, that's all it says. However it does also say there is more stuff which he/she cannot talk about but the article did say something about game modes. I'm eager to play this new expansion and see what 343i has in store for the latest in the Halo universe. [spoiler]Edit: to all the people that are complaining that it should have been there at launch, I agree with you, but it wasn't and we can't change that. What we can do is help them build it into the game you want to see it built into and not whining about how everything should have been there at a launch, but again, I agree it should have been.[/spoiler]
