It's unfortunate the Bungie isn't launching Destiny 2 onto all platforms at the same time, as the PC version of the game isn't coming out until October 24 - a good 6 weeks after the Xbox One and PS4 versions. But... this could be a good thing.
First off, we live in a world of unfinished, always-changing games. Destiny 2 will be patched constantly for the first few months, so this gives Bungie an additional six weeks of updates for Destiny 2 on the consoles to get the PC version in a better state. The game is already solid as it is, but there will be small fixes and tweaks thanks to the console gamers kinda beta testing it for us (thanks guys).
It's reaffirmed when there are updates being pushed out for Destiny 2 already, with a "longer-than-scheduled maintenance period" for Destiny 2 servers today. After this outage, Bungie baked in some new features that included the matchmaking equivalent for high-end activities, Guided Games.
Guided Games gives you a way to discover a group so that you can complete the weekly Nightfall Strike, something you think Bungie would've included in Destiny 2 when it launched. But now that it's there, Xbox One and PS4 gamers can select an icon at the bottom right of the Nightfall icon itself in the Director. You can then choose whether you want to be a Seeker, or a Guide, with a 45-minute commitment - oh, and voice chat is required.
Bungie also included some fixes for the clan roster, which is now in-game, while bug fixes have been applied to the MIDA Multi-Tool if your inventory is full when it's given to you. Another bug that was fixed now lets players get their missing MIDA Mini-Tool from Devrim Kay, while a "rare memory leak that would result in a crash" was fixed.
The PC is getting some love in the custom control setup in Destiny 2.
Bungie has been talking up Destiny 2 on the PC for quite some time now, where back in June the developer said it was making PC specific tweaks to the game It was later revealed at Gamescom 2017 that NVIDIA partnered with Bungie and Activision for the PC version of Destiny 2, with support for SLI setups, HDR-capable monitors as well as UltraWide gaming displays.
