Online trophies

[BadAssMarine13 20]

Just wondering how many online trophies there are and how difficult, as there's no trophy guides available

Only 2, one requires you to complete a wave at wave 10 or above with 4 people and the other you have to revive people 25 times. Getting to wave 30 and playing a wave on each map are easily doable offline solo so the only real challenge is finding 4 people.
