Not sure if this has been posted, but I'd like to suggest that waypoints be incorporated into the retail version. Maybe while in battle, pointing gestures can also serve as a waypoint, which can be seen by nearby players and squad members. This way we can share our discoveries of loot and spinmetal. I'd also like to say this can be used to help squad members who are low on ammo to locate any that may have been dropped by enemies. However, I have noticed that I will pick up normal ammo and my buddies will pick up heavy or special ammo in the same spot. Hopefully ammo types found will be identical for all players so that this strategy could truly pay off.
