Halo Reach Gameplay Details

Gamespot has a pretty good article and video about what they've discovered so far. Most notably is that Spartans in Halo Reach have the ability to upgrade their equipment. Unlike Bubble Shields or Flares from Halo 3, these upgrades are persistent and can be used more than once. They tease the "Sprint" upgrade which you can use and then allow to recharge. Thanks to OD for the tip.
