More companions in Fallout: New Vegas
Is there any way in which you can have more than one follower? In Fallout 3, I had four.
Solution 1:
Without the use of mods, in New Vegas you can have one Humanoid (Human/ghoul/super mutant) companion, and one of either Rex or Ed-E (robot companions).
There are several mods that increase the companion limit.
In addition, you can gain temporary companions through the use of items like the NCR emergency radio.
