Exotic Weapon Destiny...
	Farm Bright Engrams...
	The Tower...
	Various Steam Achievements...

You can access all of them in Homecoming mission. Fortunately, there is no struggle in the process. When you start playing the mission in Beta,
after landing on the destroyed The Last City, you will pass injured people. A guard wills open door for you to the weaponry, there you can pick up the weapons. Enter the armory and this is the first time you get some rifles. This is one chance to pick up good weapons before you land into the battle. So below are the three weapons you can carry.

The process to start farming Destiny 2 Bright Engrams is easy, all you need to do is to reach level 20 with the Guardians. As you are at level 20 you will see that Guardians cannot level up more but they can still earn XP. Now every time you fill the XP bar to the Max you will get a Single Bright Engram. This is how you start farming them. For the early stage you will be able to easily get 3-4 Bright Engrams and then it will be a bit difficult after some time. And if you are tired of purchasing items using the Bright Engrams then you always have the option of dismantling items into Bright Dust, which is the Eververse's specific Currency.

Successfully complete the main campaign and defeat the final Boss to unlock The Tower, which contains lots of new vendors and end-game activities.
