Questions

1 - How do I activate the observable in front of me on a PC game?

2 - How do I activate this catapult in front of me on a PC game?

3 - Do I get gear and such for the Campaign mode or only pvp?

Sorry new and so far lackluster experience.

I was having a problem with the observables too as there was nothing in controls about how to activate them. Most activatable things (such as catapults) are done by pressing (and normally holding) E but its not the same with the observables. After spamming my keyboard I found that it was O. As for your 3rd question I may be wrong but I believe the campaign characters have set gear, however progressing in the story can unlock gear for the multiplayer as you said, such as symbols and ornaments.
