What trophies can be obtained in Co-Op?

Can you get class related trophies, as sniper headshots, in Co-Op?

[Sylvanticore]

Yes you can, that is how I got many of them including the shotgun one.

I can confirm the 4 class specific ones works as well as the 500 hero kills. I did all 5 in coop mode.

Class related trophies (vanguard use with assault, commands with the officer, sentry gun kills with the heavy & headshot kills with the specialist), hero kills (500 kills with a hero) & playing as all launch heroes, 25 multiplayer milestones, first kill of the match & player level to 25 & 50 (i.e. your overall level, not that of your individual troopers) can all be done in co-op. At least that's where I got them.

 

The only one I am not completely certain about is the milestones, as I did play some multiplayer back when it released & got some there, so there might be some related to multiplayer specifically. I reckon there's some you could pick & choose to get it done in coop though.

 

As a side note, for the levelling up to 25 & 50 (as well as leveling up your troopers &/or heroes), Wednesdays seem to be the day to be on, as it seems to be triple xp every week.

 

Edit: I haven't reached level 50 yet (just in case I got called out about that!), but I just got level 25 last night playing coop & its definitely possible to do 50 as well.
