Best weapons in Marathon
Being an extraction shooter, you won't be able to pick up every gun you find in Marathon, and, of course, you can lose it all in an instant anyhow. You'll want to prioritise collecting and using the best weapons so you can better defend yourself while picking Tau Ceti clean.
As it stands, there are a whopping 28 guns in Marathon, ranging from pistols and SMGs to railguns, so there's a lot to pick from. And if you're sitting there wondering how you even begin to find good gear, I recommend completing map events during a match...
