All signs are pointing to Bungie making Destiny available on the PC in the near future, with the developer hiring a "PC Compatability Tester". Bungie has the job listed on its website.
The description reads: "The PC Compatibility Tester will evaluate PC hardware-specific features and ensure various systems work together across multiple PC configurations to provide a great experience". The developer is looking for someone that is "experienced and comfortable with building PCs from scratch".
Back at E3 2014, Activision Publishing CEO Eric Hirshberg teased three months before Destiny launched, that the PC version of the game was "something we're talking about and looking at very carefully". Earlier in 2014, Bungie writer Eric Osborne teased: "We have a lot of people who play on PCs. We have a lot of appetite to build that experience".
We shouldn't get our hopes up for a PC version of Destiny too soon, but this is definitely promising.
