Macka Bree, head scientist of the BAL of the OSI felt like he was having a brain aneurysm... News had just broken about the NCR's catastrophic loss in the Mojave, and that they were pulling all forces from it immediately... Considering his rather close proximity to the Mojave, he'd had hoped that they would have warned him sooner! Sure, sending encrypted radio signals to the base took some time, but it doesn't mean he can't complain about it!

Plus the fact that one of the people that'd defeated and utterly humiliated the NCR happened to be someone he'd offended in almost every manner possible, he wanted to escape as soon as it was even remotely possible.

Unfortunately, due to the type of work they did at the facility, they needed to get many subjects either ready for transport, or incineration. Ultimately the choice was up to him, but while he was worried for his own safety, the progress they'd made on the various experimental subjects was extensive! It'd be a catastrophic disaster to their work if they were forced to incinerate them without properly studying them first!

Thus, he'd chosen to transport their experiments back to New California, and hope that no one would notice the random heavy convoy appearing from nowhere. He wanted to leave alongside the rest of the Mojave troops, but due to how long it'd take to anaesthetize the subjects and ready them for transport in properly equipped cages.

Fortunately, the NCR's ventures in the Mojave hadn't been completely futile. The BAL had come away with a Cybernetics expert in their captive Usanagi. He'd proudly pit his creations up against the Brotherhood of Steel now that they'd been augmented both biologically and mechanically... Though, he was still unsure how they'd stack up against Bulwark... From the radio he'd heard horror stories of the battle, thousands of indestructible robots fitted with incredibly powerful weapons? Their soldiers all equipped with armour better than even the Enclaves? Or their leader who was apparently a Psyker like himself?

Macka shakes his head and continues shredding files and packing away his equipment, hopefully they'd be out by tomorrow if they worked efficiently, that'd prevent anyone from apprehending them beforeha-

*CRACK!*

The loud sound of lightning occurs from outside, causing Macka to accidentally toss his half-shredded papers in the air. "W-what was that!?" he mutters while getting up and heading to the surveillance room.

*Bang!Bang!Bang!Bang!*

The sound of discharging ballistic weaponry only makes his feet speed up, worried about who'd managed to find the secret facility...

He quickly reaches the surveillance room and looks at the wall of monitors which were displaying everything inside and outside the facility...

Most of the facility was actually underground, with the only thing visible from the surface a large, heavily fortified metal door peaking from a rocky mountain face... It looked somewhat reminiscent of a Vault, but more for private use than the one's housing Vault Dwellers...

Outside, he could see hundreds of armoured giants... Super mutants if he had to guess, all marching towards the facility... He turns an angry glare at the NCR trooper who was supposed to be keeping an eye on this, how the fuck did an army slowly march up without him alerting everyone?!

"S-sir! They appeared out of nowhere! Lighting hit the ground and they appeared from it! I swear!" the trooper quickly explains, hoping to not become another subject of the sick man's experiments.

...

The man's words cut Macka short, he'd heard rumours of how Bulwark travels so quickly, and lightning just so happens to signal their arrival, as if they were some sort of Transylvanian monster... Perhaps the trooper wasn't as incompetent as he first anticipated. "Keep an eye on the cameras and coordinate with the others to defend the facility! If you don't, we're all going to die here!" Macka commands.

It was well known that the facility only had one exit(that the others knew about), Macka knew a hidden exit but wasn't going to alert anyone about it as his research was far more important than their lives. He clenches his fist and feels his control over his body and other organic material tighten, becoming more controlled as he focuses on it... Perhaps he'd have to reveal his special abilities to his colleagues?... In the NCR's current state, it would be incredibly stupid of them to try dissect or capture him, especially when he could work for their own interests...

Hmm. He didn't know if the NCR troopers stationed at the base would be able to hold off a hundred or so Supermutants, so it'd be best if he prepared for his own battle... Nodding to himself, he quickly leaves for his laboratory, specifically where the test subjects were held.

Outside :

Afton, Marcus, and the army of Supermutants had just arrived outside the OSI facility and were now quickly marching towards the front entrance of the facility. He'd already noticed the cameras hidden around the area, but ignored them as in the end, they wouldn't really matter in the upcoming battle.

"Marcus, lead the others and make sure you only kill only individuals not on the list I provided you. I don't have to tell you how upset I'd get if you disobeyed such a simple order." Afton states, eyeing Marcus with an appraising glare.

Marcus just nods, "I'll have the men remember it, what will you do in the meantime?"

Afton looks back at the entrance of the facility, "I'll open the entrance for you, after that I'll sneak into the base and look for some people. Try not to get killed while I'm gone." he states as he breaks into a sprint towards the entrance.

As soon as he approaches the entrance to the facility, auto-turrets appear from the rocky mountain wall, all firing at him with high calibre bullets.
