// Celestia plays Plague Inc: The Multiplayer 
// Story: Celestia plays Plague Inc.

It's been 2 months since Twilight mastered Plague Inc and is interested to play more, but that's just "want", not "need". So she is able to control her wants and needs. She needs to learn, anyways. She doesn't need to play. However, Celestia kept playing Plague Inc during break. Now that she had beaten the game in Cure Mode, and... haven't beaten the game in Normal Mode, it's time for something different...

She tries the Bacteria again.

Celestia hopped on Plague Inc and chooses Bacteria to start out an outbreak. She wonders if she still have that pity feeling or not. If she do, she will stop immediately. But if she don't, she will eradicate humans for sure.

Then she hovered her mouse over Single Player and noticed... a Multiplayer button?

"Plague Inc can be played multiplayer?" Celestia mumbles. So she grabbed her telephone and yes, she wants to try it out on her sister, Luna.

"Hey Luna, uh, I just realized Plague Inc has Multiplayer mode. Do you wa-"

"THOU HAST JUST DISCOVERED??" As always, Luna feels superior when it comes to games.

"Luna, I'm a newbie."

"Oh- our apologies. Do you want to try it out?"

"Of course! I'll choose- oh wait, I haven't beaten the game in outbreak mode."

Luna laughed.

"I guess I'll just go with Bacteria."

"And we shall play BIO-WEAPON!"

"Whoa chill Luna, I know you are professional gamer but that doesn't mean you can be arrogant."

"Well you know my personality. I'll name my plague... The Lunar Death."

"And I name mine TO THE MOON WITH YOU!"

"Okay are you mocking me yet again?"

"Sorry, heheh. Solar Plague, it is then"

"Much better. Well then, let's start."

"Okay, I'm ready."

Then the game starts. By this point, Celestia chooses to start the outbreak in Kazakhstan, while Luna chooses China. Upon starting, none of them both knew where their opponent started the plague. Their objective is to infect as many people as possible and catching up with their opponent, or infect slowly and let their opponent eradicated first. Either by cure or lethality of the plague.

So yeah. The pathogen starts out weak. Celestia proceeds to evolve Livestock first as the trait is the cheapest yet moderately effective in rural countries. Luna however, must wait until she gets DNA points to evolve mosquito.

"Sooooooo Luna, what are your plans in this game?"

"Just as usual. Infect as many as I can and kill very slowly. And when I spotted you, you're doomed."

"We'll see about that."

"Your dessert for a month if I win."

Meanwhile Luna mumbles away from the phone. 'Surely I will win. Prepare the dishes, Celesti-'

"And what if I win?"

"You can decide what to do for me and the timespan for it."

"Deal. I must focus and think about that later."

"Oh don't be so sure you will win. Chances of you winning against me is 5 out of 100."

"Aren't you supposed to use "we"?"

"Forget the we. Now it's me and only me."

"Mmm'kay"

So that Luna got enough DNA points, Luna proceed to evolve Air instead of Mosquito. Airborne diseases have higher chance of spreading by airplanes. Luna is intelligent by means of game strategy.

While Celestia is just leaning on her back, Luna already outnumbered her in infection. Celestia only infected 250, while Luna infected like 5720.

"Luna you outnumbered me."

"Ha, what did I tell you about games?"

"Don't be proud. Even if you found the origin of my disease and you got cured few moments later you still lose."

"We'll see about that."

"Aaaaand you copied me."

"We'll see about that too."

Now this is just the beginning. Celestia finally evolves water and air after getting enough DNA points and her plague already infected Russia and Middle Asia.. While Luna's plague is still in China.

"Luna I think my plague infected like 3 countries by now."

"And how many infected people are there?"

"Oh like, 2000." Celestia is too lazy to read the whole number. It's accurately 2658.

"Jokes on you, I had 10000."

"Welp."

Celestia continues to play as calm as possible, unlike Luna, who has been slamming her keyboard and switch for losing a match in CS:GO 2, is worried that she would lose her opportunity to win dessert for a month. If she won, it's worth it. But if she don't, then nopony knows what happens next. She is worried that Celestia would dare her to be a maid for a week. Or a month.

But that's literally not neccessary for Celestia by this point. Luna however, loses concentration and is unable to control her plague just because she is thinking what the dare might be. Worst options possible are Luna will be sent to the moon. But that's nearly impossible for Celestia since she loves Luna so much that she didn't want to lose her for the second time.

Back to the game, Solar Plague spotted The Lunar Death. Which is, a significant setback in infection rate for The Lunar Death.

"Aha! You're from China, aren't you?"

"H- how? HOW??"

"Calm players winners."

"Heh"

Solar Plague significantly became lethal by the time The Lunar Death is spotted on China. So by this point, Solar Plague got a +32 bonus in infection rate, while The Lunar Death got -10 penalty. In a few minutes, it must be the Solar Plague who outnumbered The Lunar Death.

Since then, Solar Plague had been making DNA points out of infection. Each day with roughly +3 DNA points. Soon Celestia evolved Air, Air 2, and Water. Planes and ships now prone to the disease, even though they are already sanitized.

~Few minutes later~

"Okay Celestia, you outnumbered me. How dare you."

"So eh, this is a piece of cake, I suppose. I shall start evolving some symptoms."

"I'll do it too."

Both evolved Coughing and Sneezing. Luna expected The Lunar Death to be lethal, so she evolved not only both symptoms. Insomnia, Cysts, and Anaemia are also in the traits. While Solar Plague is expected to be a 'hot' disease, so fever comes into play.

"Okay what penalty this is I got..." Celestia mumbles. Luna overheard it.

"Ha, you are more prone to cures! I shall kill these 2 million humans with my death plague!"

"Luna you better infect half of the world before you do that."

"Well what? You already infected like... 7 million. Impossible for me to catch up."

"Hot weather and cold weather, Luna. You need to maintain your plague's abilities. Not just transmission and symptoms."

"WHY ART THOU HELPING ME? Shouldn't you try to take me down?"

"As an opponent, yes. But as a sister, no, so it's a no."

Luna feels the love. Now the competition is not like war between two countries, but now it's more like an olympic. "You- made me flattered."

"Ah, you. Always has been."

By this point, Luna actually don't want to beat Celestia, but for the sake of her delicious desserts she must do it. So yeah. Since her plague is Bio-Weapon which kills everything it touches immediately - more lethal than Ebola - The Lunar Death is losing infected people due to early lethal evolves. Which is, a big blunder. Especially for plagues which are not yet a pandemic.

"By this point you made me lose, Celestia. Your charm is dangrous when we both are playing together against each other," Luna stated while blushing.

"Gosh why are you so dramatic, Luna?"

"Celestia, I'm not. And I'm not a drama queen."

"Is that true? Your voice is just like you're making up your expressions by this point."

"Oh haha."

So yeah. The Bio-Weapon is the worsf choice of all actually. Even with no 'symptoms', the disease is already dangerous as it bashes everything it touches. Just like radiation from nukes.

"Celestia, I lost the match."

"You lost?"

"Yes. Bio-Weapon is particularly a worst choice for multiplayer."

"No it must be because of you evolving symptoms just too early."

"The description says the pathogen kills everything it touches."

"Geez that could make a weapon for Equestria-"

"Sister, it kills literally everything it touches. It means innocent ponies, our civilians, allies can be dead from it."

"So eh, about the dessert for a month."

"Yeah I'm not going to have them."

"You can say that again, but I dare you to... eat my cakr in under 5 minutes without vomiting any piece of cake out."

"That's- That's a torture, sister!"

"I won, Luna. I won. But well, let me change the demand...

As they are talking, the unexpected happens. The cure for Solar Plague is finished, therefore the infection rate drops. And Solar Plague only killed 2k people, while Lunar Death kills like 3m over the time. Celestia and Luna does not notice this.

"...to something simpler."

"What is it?"

"Be my maid."

Luna sighed. "I knew it."

Few moments later, a screen saying Luna won and Celestia lost appears.

"I- won?"

"Wait... wasn't I the one winning before?"

"You got cured, Celestia!" Luna jumps from her gaming chair and hops around her room with joy.

"Well, my dessert for a month then."
