[quote]Try running around with a shotgun as a titan, see how far that gets you[/quote] Actually, it got me quite far. That's how I completed mine. But, nothing is forcing you to try and get it done with a shotgun. You can snipe, fusion rifle, lmg, hell, I'm pretty sure even your super counts. If you're getting dominated or you're placed on a map you don't do very well on then unequip The Last Word. Kills and deaths only count if it is equipped so you don't have to worry about losing progress when switching to a different primary.
