Aye boys and girls! Welcome to my SAS 4: Zombie Assault x RWBY Crossover!

I'm very new to this kind of thing so excuse any errors. Also I might forget about this so expect hiatus(?) almost every time. Still have to maintain my account 'Combine-117'. I just feel like I'm gonna use that name a lot, because it feels cool, heck I'm gonna use that for this story! So yeah, My name is almost always 'Combine-117' or 'UU-117', which stands for Universal Union-117, so you might see me sometimes in games.

So... On to the chapter!

A figure is seen walking down a hallway. While it might look normal, if it didn't look like a zombie.

Shambler. A term given to the SAS members for its slow pace, the third weakest of the infected. It might not be that powerful as it relies on numbers and slapping the enemy to death, it still has enough blunt force to damage SAS members.

It is seen walking down a hallway, no aim whatsoever. Until shambled upon a hangar filled with infected, some could be seen fighting with some watching it. The Shambler shambled towards the circle. Two stalkers were facing off with each other.

Some people say that it looks unusual, but in the infected's world if you're a high-level infected, infected would look up to you and follow your commands. The two stalkers were facing off with each other to see who is gonna be the leader of the group. The fight went a little while until they heard it.

Standing at the entrance to the hangar stood a figure with red lights, clutching a sniper with glowing sides and center. In front of him, lay a bunch of dead infected. The many living infected looked towards the intruder.

And moved towards the figure with the best speed possible.

The figure seemed ignorant to the horde and calmly lifted his rifle. The trigger was pulled and out came a blue bolt. The bolt struck many undead/infected and even pierced through them, but what was most probably the sight to see was electricity coming from the bolt each time it passed through an individual, hitting numerous undead with even more volts of electricity. He shot more bolts to the surviving undead

In a few seconds, the horde was nothing more than heaps of bodies, guts and other disgusting stuff.

The figure looked at the heap and walked away to the next hallway which would lead him to the control room. After encountering a few infected along the way he saw the control room, moving towards the door. He reached to open the door, but it was blocked by something. Confused, he said out loud to the potential survivors.

"Hey! Anyone there?"

He swore he heard some shuffling and a girl saying something about 'dolts'. Confused about that, but more annoyed that they did not open the door to let him in as it was still blocked. He called out again.

"Stop blocking this door so I can come in!"

Meanwhile, a Shambler snuck up on him, but was retaliated with Double-barreled shotgun pistol. The Survivors must have heard it, because he heard an 'eep!' and something her to keep quiet. Growing irritated, he tried one last tactic. It was used when he was that irritated and desperate.

"Hey!" he hollered, "you open this door or I'll blast it open myself!" He cocked his LMG, which was for bigger infected, at the survivors.

It must have scared them a lot, because the door was open in no time. The mercenary expected a bigger group, but all he saw was two girls. One of them looked scared and sheepish and no older than 15. The other looked angrily at the 15 year old, 17 it looked like. Confused as hell, the mercenary brought out one word.

"What?"

Okay! First chapter is done! Woo!

Sorry for the cliffhanger! But I want to make this a warm-up and I wanted some feedback, before continuing this. Please suggest some ideas on what you think, I might actually use if want to.

So bye! :D
