And then all hell broke loose..., When runs go wrong. Options

[FuelDrop]

Hey there!
As regular readers may have noticed I'm very fond of sharing war-stories about runs, and not hesitant to create threads around them.
Here's another one!

Once upon a time, our group was tasked to infiltrate a Lone Star server farm. While our less subtle members created a distraction around the front our stealth experts crept in through the back, down to the secure basement, and into the security center where we disabled several guards. Then we split up, one going to do the mission while the other raided the Lone-Star armoury to lay down a fake trail. That elf was named Nitro, and this is his story.

Nitro busted into the armoury with blade in hand, ready to disguise our true purpose in coming with a shower of blood (don't ask me why, he just likes blood. he's one of those 'lovable sociopath' types). The SWAT team inside are unprepared for such an attack and fall easily before one of the best swordsmen in the world, and at the end of the round but one man remains. This officer (we never found out his name) grabbed the nearest object and threw it at Nitro, who dodged easily. The object in question? A grenade, which the officer had the presence of mind to arm before throwing.

Now being a Ninja, Nitro's first reaction was simply to backflip through the doorway and slam the door closed, waiting for chunky salsa to take care of the guard for him. Unfortunately, the server farm was lax about it's storage procedures and as a result the grenade landed next to several boxes of EX-EX... which were in turn near their stockpile of assorted explosives. The resulting bang shook the building to its foundations, ripped the reinforced steel door from its hinges and sent it slamming into Nitro, flattening him. Joel, the man who'd been busy at the computers, rushed in to see the armoury burning and Nitro unconscious next to it.
"WTF?!?" he exclaimed, slinging his friend over one augmented shoulder and running for the exit.
Once out of immediate danger he revived Nitro, and the pair fled upwards towards the main complex and freedom. At the top of the elevator shaft they encountered some panicked Lone Star employees with SMGs, who promptly sprayed the runners with a lead-based welcome that sent Nitro once again into dream land. Joel dispatched the pair but spotted their cavalry making their way through the entrance. Slinging Nitro over his shoulder once again he demonstrated his preparedness by detonating the breaching charge he'd placed before entering in the hopes of distracting the newcomers while he fled to the roof and the waiting helicopter.

Then the building collapsed.

Apparently the damage from the initial explosion had been severe enough that it had compromised much of the building's structural integrity, and that breaching charge was the straw that broke the camel's back. The entire front of the building collapsed, knocking Joel prone, sending Nitro to the brink of death, and burying the 300 or so wage slaves assembled in the underground carpark under many tons of collapsed brickwork. Joel struggles to his feet, grabs Nitro, and hauls him up to the waiting extraction chopper.

And the incident was never mentioned again. Ever. Well, until now anyway.

It was the first time we'd screwed up a run that badly.

Anyway, this thread is for stories of times that the run went completely to hell (bonus points if it's directly or indirectly due to your own actions). We pass no judgement here.
