Welcome to my step by step spoiler free guide to what I would consider the best narrative experience in Mass Effect.

As a warning, I will not be including all of the fetch items missions in this guide. I personally find them super time consuming, so if you want to collect everything (I think only one has any knock on effect at all in future games, but it's negligible) and explore everywhere that you land in the Mako, feel free to do so but you will not find it in this guide. (I tried to do it once, and got 40 minutes into the grind before giving up entirely.)

While the NPCs don't have as much to say as in subsequent games, I would recommend talking to them all where possible. Where a choice of companion has a big impact on the mission, or some unique dialogue, I will highlight them.

Some of the missions here do not trigger until you jump into a system. If it looks like something might not have triggered, jump to another system and you might get a message.

Be sure to look everywhere for boxes for upgrades and mods to your weapons, and keep reducing items to omni gel when you get some higher power items.

If you're looking for character builds, I highly recommend this reddit post. If you want to do it on your own however, the only thing I recommend is maxing out either Charm (for a Paragon leaning Shepard) or Intimidate (for a Renegade leaning Shepard) as soon as the points become available. Also when Spectre levels become available take 4 levels in that.
