Are there any multiplayer achievements?

[Kaidan]

I'm at my first blind playthrough and try to avoid spoilers and guides. I'm pretty far into the game and already at "meta" level 150. I mostly play solo and don't care much for pvp. Will I miss out on any achievements or unique items if I continue leveling past 150? Are there any items or quest locked behind multiplayer or can I get everything offline?
