A while ago I gave Mr. House the platinum chip and sat through the accompanying cutscene. After wandering around the strip, I noticed only about half of the securitrons were still Mk.I's. The gatekeepers and ones in the Lucky 38 all upgraded fine, but it's a wash everywhere else.

They are still weak no mater what. When I first saw the upgrade I was like, "Finally a fight I can get a challenge from." Then disappointment came.
