You can pick Cassidy up in Vault City, and he's well worth your time to do so. Speak with him about his bar, and then offer him a place at your side.

Similar to Tycho from the first Fallout, Cassidy is a fantastic shot with any small weapon (shotgun, sniper rifle, or gauss guns make good choices). His only drawback is slightly lower hit points than other NPCs and the fact that he can only use stimpacks as drugs due to his heart trouble.
