Fallout 3!!! Other than the obvious Deathclaw, what do you find the hardest creature to kill?

the sentry bots are definitely a pain also like you said the mirelurks and the yao guai because the move so fast and have quite the jump range.usually i use the xuanlong ault rifle or a combat shotgun for the mirelurks and the yao guai but the sentry bots you need to use pulse grenades on them.hope this helps.good luck in the wastelands.
