So far we've had Solo, Leia and the Emperor potentially leaked. Is Yoda in there too?
Achievements and/or trophies in the file seem to suggest more variety to the missions, with mention of Endor chases (speeder bikes are also mentioned) and a 'Beggar's Canyon mission.
It's not clear if line 630, "your account is banned" refers to a Star Wars specific thing, or a console-related punishment. Either way, best keep the toxicity to a minimum.
Here's what appears to be more solo/co-op missions. They all seem to be unlikely candidates for any new surprise multiplayer modes - Probe Droids and Dark Side in particular clearly aren't going to work as a Vs mode. You can see the previously mentioned Endor Chase and Beggar's Canyon missions mentioned up there, as well as the base-taking Overpower and some sort of hero-rescuing Extraction.
New toys 1
Several weapons are mentioned. The charging sniper-focused Pulse Cannon sounds interesting.
More toys 2
Two things worth pointing out here. Firstly the mention of the Wookie Bowcaster. It's been in most Star Wars games so it wouldn't be a huge surprise to see it here. That Cluster Shot also stands out, giving your primary weapon explosive bullets by the sounds of it.
These are the droids... Oh God, I can't do it
More on the Droid Patrol mission, The R5D4 droid is the one that explodes, forcing Luke's uncle to buy R2 instead. The Viper is the spidery one at the start of Empire.
There are some more weapons listed between 2107 and 2020. The Jawa blaster sound a lot like a shotgun while the T-21B might be a solid mid-long range option.
Traits are a new thing and appear to be a kind of Star Card. It's possible they might be like the Sharpshooter option from the beta. That had three increasing levels that reduced ability cooldowns when you scored concurrent headshots.
Battlefront is meant to be a classless game, using Star Cards to tailor your character. So I've no idea what this is. Possibly something linking into those Traits in the last slide.
