-Somewhere in Philadelphia-

In a university somewhere in downtown Philadelphia, Bruce Banner is working on a technique that'll hopefully control his transformations with better effect. He sits on the floor and assumes a yoga position and starts to take slow, long breaths. "Hopefully this'll help us come to an arrangement..." Bruce says to himself when an explosion randomly occurs in his lab, knocking him out.

-Many Months Later-

Bruce wakes up in a hospital room, though it's eerily quiet. After disconnecting his IV and painfully pulling out the catheter, which he did not enjoy at all, he comes across a grisly sight- a nurse laying on the ground. Dead...with half her head caved in like it was repeatedly bashed with a heavy object. Bruce's mouth fills up with vomit as he puts his head in a trash can and pukes it out, coughing numerous times afterwards as he tries to process what he just saw. "Oh, God...What the hell is this? What happened here?" He asks as he tries to remain calm. He eventually regains his composure as he puts his clothes back on and exits the room. The hallway was filled with dozens of corpses, maybe in the low hundreds. Not just other patients, but nurses, doctors, civilians, and even military officers and soldiers. Whatever happened here wasn't an attack. It was a massacre. Unlike before, Bruce kept himself from gagging again, fearing whoever or whatever did this was still in the hospital. "What happened here?" Bruce asks in his mind as he finds an exit.

Once outside, various moaning can be heard, though Bruce kept quiet, fearing the moans were from whatever massacred all those people inside. Bruce manages to find some submachine guns laying on the ground, as well as a blood soaked machete, which he picks up before heading into a dark alley...

-Dark Alleyway-

Bruce wanders the alley, coming across even more corpses like at the hospital. "God...What could've done all this? How longbwas I in that hospital? It couldn't have been more than a week..." He says to himself as he inspects his new surroundings. Four people carrying various guns walk into the alley, coming across a corps with its hand pointed towards the sky, its thumb having been gnawed off. Unlike Bruce, they didn't seem to mind. Clearly they're more experienced by this than he is at the moment. One of the people kneels down and inspects a strange green substance oozing out of the body.

"Never seen anything like this before..." The old man, Bill says as he rubs the goo on his fingers.

"Jesus. Don't let that stop you from smearing it all over yourself." The second man, Francis says in disgust at Bill's morbid curiosity.

Possibly offended, Bill sneers as he rubs the goo on Francis' jacket. "They're changing!"

"Ugh! Damn it, Bill! Oh, it stinks!" Francis says in disgust as the third man, Louis, giggles at his misfortune. After that, footsteps could be heard.

"Quiet. Listen." Bill says as the group ready their weapons. Much to their relief, it's Bruce, who slowly approaches them. "Glad to see someone else made it."

"Yeah. That makes two of us." Bruce says as he looks at the group, which comprised of three men and a young woman. "Do any of you know what the hell is going on?" He asks, to which they all shrug.

"We know what's going on...but we don't know what caused it." Bill says. "How'd you not figure this out for yourself sooner, kid?"

"I was sleeping in a hospital bed. I woke up...a nurse's head was bashed in..."

"My God..." The woman, Zoey says, saddened by how Bruce was introduced to all this. "I-I was in college when this happened. My roommate caught this. This...disease. I had to bash her head in with a bat. I know how traumatizing this is." There was little time to mourn though, as a woman could be heard behind a door, crying. "Someone's still alive...!" She exclaims.

Bruce stays outside as Bill and Zoey open the door and enter the dark room behind it. "Over there." Bill whispers as they use the flashlights on their guns to illuminate a path for them. As they venture further into the room, the crying gets louder until a convenient bolt of thunder reveals the source of the crying and sobbing- a Witch. Bill quickly turns off their lights. "Flash off." He firmly whispers. Luckily, the Witch doesn't take notice of their prescence.

As Bruce, Louis and Francis wait for Bill and Zoey to return, several Infected come running full sprint towards them. "Oh, shit! Shit!" Louis and Francis say in unison as they, along with Bruce, fire on them. Louis runs into the building, idiotically startling the Witch, who shrieks in anger at him.

"Run like hell!" Zoey screams as her, Louis, and Bill make it out of the room just in the nick of time and close the door in front of the Witch, but she easily punctures the metal door with her claws and swings at Louis, who fires his Uzi into the hole, unloading on her as Bruce and the other survivors fire on the ever growing number of Infected, who pour into the crammed alley from both directions. Realizing that they are severely outnumbered, Zoey reaches into her pocket, pulling out a pipe bomb. "Fire in the hole!" She yells loudly as she hurls the pipe bomb several feet away. Much to Bruce's surprise, the Infected start crowding around the small object as it detonated, killing many of them, but also staggering the survivors due to its blast radius.

Louis notices an evac helicopter passing overhead, foolishly running out into an empty street alone in an attempt to get the pilot's attention. "Hey! Over here! We're not infected! Down here!" Louis hollers out. However, it was in vain as the pilot didn't notice him and flies onward, much to Louis' frustration. Unbeknownst to him, a Hunter was stalking him, leaping from building to building to get a good position so it could attack him. It leapt from a tall building overlooking the street Louis was on before leaping onto him as it began to tear at him with his clawed hands. Before too much damage could be done, Bruce and Zoey knock the Hunter off and fire into it until it falls on a car, setting off its alarm.

"Shit!" Zoey exclaims as screams from the Infected could be heard as their shadows were illuminated by several car headlights. As the survivors all huddled together for a final confrontation, a roar could be heard. It was deep and guttural, but it wasn't coming from Bruce.

"Don't tell me that's what I think it is..." Francis says nervously, thinking that the origin of the roar was a Tank. Almost as if in answer, it did turn out to be a Tank. The gorilla-like Infected roars again as it hurls a car at the survivors like it was a mere toy, knocking down a fence that a group of Infected was climbing. Bruce and the others run into an alley to escape. Things go south as the Infected tackle Bruce and pile on top of him, biting into his body. Zoey spins around and screams in horror as Bruce is devoured. His screams stop, only to be replaced with deep growl-like breaths as he transforms, sending the piling Infected flying in all directions. Bruce, now in Hulk form, spins around to face the Infected horde as well as the Tank. He roars as he charges into the horde, swatting the smaller ones aside with barely any effort being put into his attacks. A minute later, and the only Infected that remained was the Tank, who ran past him and had the survivors pinned, keeping them from escaping to a rooftop that would be too high for them to follow. The Tank raises its arms, ready to crush Francis, only for Bill to release a barrage of bullets from his M16, stunning it long enough for Hulk to toss it against a wall and repeatedly punch it in the head and gut with blows that practically shook the entire alley.

"Go! Now!" Hulk roared at them, urging them to climb up a ladder that'd take them to the roof as he and the Tank plow into a wall.

"Go! He's got our backs!" Zoey says as the others use Hulk fighting the Tank as a distraction as they make it up to the roof. Hulk continues to trade blows with the Tank, eventually finishing the hideous creature off for good, grabbing it by the head and slamming it onto the ground as much as six times before ripping its arms off. Defenseless, the Tank could only scream in pain as Hulk sandwiches its head between his massive fists, crushing it to the size of a walnut.

"Shit!" Louis exclaims in response to the brutality. Hulk hears him and leaps upward, landing on the building. They all turn around and aim their guns at him, even Zoey, despite the fact that he saved their lives.

"I save your lives, and this is how you thank me?" Hulk asks sarcastically, crossing his arms across his chest as he stares down the survivors. "By pointing your guns at me?"

"Well...w-when you look like the Jolly Green Giant on steroids, it's understandable to not trust you, man." Louis says nervously, to which Hulk lowly growls.

"W-Why did you help us escape the Infected?" Zoey asks, pointing her dual pistols at Hulk's face.

"Because they attacked me." Hulk says, giving away that he and Bruce were one and the same.

"Wait. You're that guy we met in the alley!" Francis exclaims as he lowers his shotgun, deciding to trust him. For now.

Zoey lowers her handguns and holsters them after deciding that Hulk wasn't a threat to them. "Sorry about that, big man." She says apologetically, receiving a silent nod from the giant.

"What now?" Hulk asks, unsure of what their next plan was.

"Well, son..." Bill says as he lights a cigarette. "Our best bet is getting somewhere safe, preferably a military base or a prison. This rooftop won't protect us from the flu, let alone...whatever caused all this. We'll stay here tonight, but tomorrow we find a more permanent safe haven. Got it?" He asks Hulk, who nods with a slightly audible grunt.
