The whole gang

Finished off today the companion quests (more or less) and also took care of some other achievements.

First off I took all the money I had and went to the major weapon dealer and bought every weapon mod they had, and the weapons that they were for. I then waited 3 days for them to restock and repeated this until I had the weapon mod achievement. I didn't bother keeping that progress since I can kill a deathclaw with 2 punches so having a slightly lighter hand gun was pointless.

After reloading my previous save file I went off to find Raul Tejada, the ghoul mechanic. He was being held prisoner by a crazy Nightkin running a radio station, but after I fixed the Nightkin's robot I was free to make Raul a companion. His quest line needed to be first unlocked by talking with various people who were getting on in years, after this he told his life story and realized that he still had some fight left in him despite being a few centuries old.

Then with Raul in tow I went after the quest to get Rex, the cyborg dog. The quest line was rather simple, after doing a job for The King I was allowed to look into a way of healing the dog. After a few quick travels I brought Rex to the doctor that introduced me to Lily and finally made use of the dog brain that I've been carrying around in my bag for weeks.

I then Picked up Ed-e, the military Eye-bot, after a quick fix up job and then convinced the doctor Arcade Gannon to join up too. Ed-e's quest required me to talk to several people and then wait several days between each person, then after several days of doing this Ed-e returned to my party fully upgraded. Arcade's quest is only triggered near the end of the game when I'm planning the attack on hover dam, so he's just around as an extra gun for now.

With all the companions registered I got the achievement, so I then went hunting around to collect up all the snow-globes for that achievement too. Also along the way I got the speech and computer hacking achievements, so all that's left is to win 30 hands of the card game Caravan (which I have not played once) and finish the game as an independent.
