5. Make The Companion Gameplay More Varied
Unlike your faithful companion, Dogmeat, in Fallout 3, your allies in Fallout 4 are invincible. Straight out of the Skyrim mould, you could load up your companion with all the junk you didn’t want to carry and had the option to choose from a whole host of different characters to travel with.
There were so many companions to choose from, each with their own set of loyalty missions, that you could easily play through the entire game and not come across all of them.
However, apart from one or two skills they could use, like lockpicking or hacking, there was no real difference between all of these companions. Gaining their full trust (or starting a relationship with them) did give you a unique perk, but in terms of combat tactics or abilities every companion played the same.
The companion system in Fallout 4 was good, but to make it really engaging in the next game there needs to be a variety in each character’s gameplay. Have some companions choose stealth tactics like sneaking up on enemies, then have others just dive head-first into a gun battle. This will give the player a reason to select specific companions for certain missions, rather than just choosing the one you like the most.
