I was peeking over a ledge with an AMR and had explosive rounds on. Needless to say i lost an arm.

I was placing satchel charges at the entrance of the quarry to trap deathclaws, unfortunately I underestimated their speed. So as I ran back to the entrance the deathclaws caught up quickly, set off the traps before I could reach a safe distance, and basically brought me done with them.

well i forgot to turn on god mode when i was falling down from the sky after i went 4 a skywalk with the collision cheat and i got instadeath... well at least i fed some geckos with my cadaver

Once i jumped on a barrel with low HP and died. Remember barrels can kill too!

Unfortunately, I have done this a couple of times and it is annoying.  I have had a missile launcher or fatman equipped and have been startled by a ghoul, raider, deathclaw, etc. appearing right next to me.   Reflex usually kicks in and the weapon fires, hitting a nearby wall and detonating right next to my character.  I see my character dying right next to whatever startled me.  That's annoying and frustrating if I haven't saved in a while.  Just my Opinion!!!!  Cheers!!!  V/R  MistTiger

I was running on low health during one playthrough, jumped from a fairly small hill, broke my ankle and then somehow wound up dead. I figured if my character could survive Deathclaw swipes and shots to the abdomen, she could certainly survive a little leap, but apparently I was wrong this time. .__.

On Fallout NV I spent 20 minutes clearing out the quarry, and right near the end, while im picking up the deathclaw eggs my character ragdolls, as it turns out I forgot to kill one of the deathclaws, and it waits till the end to kill me, worst part is I hadn't saved since I first got there

I was in one of the Modded Vaults and i accidentally threw a time bomb(don't ask me how) and i just ignored it, thinking how much damage can it really do... well.... little did i know that in the other room where i threw the time bomb there was a nuclear warhead , ragdolled would be an understatement, it sent me out the map then my game crashes

i was clearing out the fort and i must of missed some one and when i was walking out i got ambushed by a legionnaire and my health was low and i had ran out of stimpacks so he got lucky

In new vegas I had just cleared out the quarry junction and barely had any health left and I was high up on one of the ledges and before I saved I fell off the ledge and had to clear out quarry junction again.

I was trying out Project Nevada's hotkey grenade feature, so I went to Primm and cleared out some powder gangers to get some dynamite. I threw the dynamite at the ground trying to hit an enemy, when it bounced back at me and killed me. :/

I remember my first playthrough of Vegas I went into Deathwind Cavern not knowing it was full of deathclaws. I was level 5 with ED-E as my companion. My only weapons were a broken laser pistol and all the preorder packs. ED-E went down immediately. I spent a good 10-15 minutes shooting the deathclaws with my grenade launcher while using ED-E to hold back all the deathclaws unbridled rage. When I was finally done I had one point of health left and no stims or food. As soon as ED-E woke up all the deathclaws glitched out something hit me in the face and I died

The only way I hate to die in New Vegas is to step on the freaking mines, which are mostly unseen.

Hmm, i would have to say the legion assassins really grind my gears!

In my first playthrough I walked out of doc mitchells house and fell through the ground

I had the camera in 3rd person and viewing from the front and was running jumping. I was just watching the jump and fall animations and got lost in thought and ended up jumping off a high ledge in Red Rock Canyon. Splat.

I was inside Repconn at the basement about to kill Nightkins, i started to setu a nice little trap, 5 mines, 3 charges, 2 plasma mines and just when i was placing the last mine, a nightkin ran directly towards me and everything exploded in my face killing me.

I have realistic head shots mod on so every now and then I'll get hit in the head and dropped by one bullet, it's a very unexpected lights out.
