Big thank you to all those who replied to my q's. Can I ask, are legendary and exotic drops only found in strikes or will the solo campaign provide them as well?
It's kinda awkward to answer, as we still don't know exactly how the loot will work, but I'll take a stab.
So the basic flow will be: play through the story and it will take you through unlocking all the main areas in the game. The missions themselves will give you rewards, and you will also get engrams (engram = loot package that decodes into gear/guns) as you play through. In D1, blue (rare) engrams had the chance to decode to purple (legendary) gear. But you will also have all the free roam areas and activities to check out for loot as well.
The further you progress, the better the rewards will become e.g. you will kill a high level mob at the end of a mission and he might drop a purple in addition to a blue engram, as well as you gaining the reward for completing the mission itself. Another example, in D1 completing the final story mission rewarded all players with the same purple primary weapon.
Now along the way, you will get assigned various quests / tasks / bounties etc from the various NPCs in the game. These may also be a source of purple gear, or give you a currency that allows you to buy purple gear from the vendors.
Now exotics are much rarer, I doubt you will get one just playing the story missions and
nothing else. But in D1, Bungie put in various different ways of obtaining them, many of which could be found during solo play. A few examples:
- Upon redeeming bounties, there was a small chance that you would also obtain an exotic quest line. This is then a series of steps that you need to carry out, go here, collect this, kill this, perform x number of this etc
(edit: this is the only way you will obtain this specific exotic, e.g. you cannot buy it or get it as a drop)
- Throughout the game, over time, you would collect a rare currency called Strange Coins. Every Friday to Sunday, a NPC would appear at random locations in the social spaces selling exotic items for Strange Coins.
(edit: In D1, the NPC would only sell "drop chance" exotics. So if there is exotic from the raid, this NPC will never sell it)
Hope that helps a bit.
