Forum:Acquiring 'This Machine'. I may of messed up

I was working on the quest 'Dealing with Contreras' and i think i messed up preventing me from getting 'This Machines', which i really want (because i use rifles the most). When i was alerted that the train had the bomb, my science level wasn't high enough to fix it. The quest appears to have concluded without me getting the weapon.

Did i ruin my chances of getting this weapon, or are there other steps I can take?

The monorail blowing up is in a different Camp McCarran quest - 'I put a spell on you' (and as far as I know you can't prevent the monorail from being destroyed). To get This Machine in 'dealing with contreras' you either need to do what Contreras says or hand evidence of Contreras' dealings to Lt. Boyd. Do not hand Contreras into Keller as you will not receive This Machine. Its a great gun, probably my favourite in the game.

Erm, you can prevent the monorail from being deatroyed. It's pretty simple. --Wiseman of the Wastes 11:34, July 29, 2011 (UTC)
