I've just got this game, I'm only level 5 but I feel like I'm missing something. I see a lot of NPC's on the tower but nothing is really explained.
What are emblems?
I'm able to harvest stuff, what is it for?
Do all items level up or just greens?
Do stats matter? What should a Hunter go for?
Why do level 25+ players kill all of the level 1-5 mobs?
How do I communicate with other players?
Also any tips on getting good early armour and weapons?
Welcome to the bizarre world of Destiny where no-one knows why they're playing
Emblems - if you go to Options->Roster it shows you a list of players in the "zone", the emblem affects how they appear on this list.
Harvest - it's for upgrading high level weapons and armour. If you see it, harvest it. It's a pain farming it later.
Items - only green and above level up AFAIK.
Stats - which stats? At level 5 I didn't think equipment had stats on it.
The Bounty system encourages high level players to go back to the newbie zones - you get the same bounties at lvl 30 as you do at lvl 5 i.e. do 6 cosmodrome patrols. It's high on my wishlist for a lvl 20 version of each zone for high level players cos it does kinda suck.
See the Destiny multiplayer thread, add some people, join their fireteam and speak over voicecomms seems to be the easiest way to communicate with players. Don't forget you have four emotes on the D-Pad - Up - Wave, Left - Point, Right - Dance, Down - Sit.
A good tip for weapons/armour *while you're levelling up* would be to look online for the golden chest locations and get them all. There's 5 in each zone.
