Points of no return

Finishing 'The House Always Wins IV' or 'Render Unto Caesar' past the initial stages: Triggers 'Don't Tread on the Bear!' which permanently locks out the NCR storyline achievements ('For the Republic, Part 2' and 'You'll Know It When It Happens').
Progressing too far into the NCR ('For the Republic, Part 2') or Mr. House storylines: Triggers 'Beware the Wrath of Caesar!' which permanently turns Caesar's Legion hostile, locking out 'Render Unto Caesar' and 'Arizona Killer'.
Killing or permanently locking out Mr. House during Wild Card or NCR questlines: Permanently fails and locks out 'The House Always Wins'.
Commencing the final assault at Hoover Dam ('All or Nothing', 'Eureka!', 'Veni, Vidi, Vici', or 'No Gods, No Masters'): The battle ends the game immediately with no post-game free roam, making all unearned base-game achievements inaccessible on that save.
Leaving the Sierra Madre (Dead Money DLC) at the end of 'Heist of the Centuries': The Sierra Madre Villa, Casino, and Vault can never be revisited, permanently locking out missed collectibles and DLC achievements from that area.
