+# Plague inc
+
+## Présentation
+
+De l'Anglais 'Plague' virus, ou peste et 'inc' diminutif de 'incorporated' peut être traduit par coopérative ou entreprise. Vous voila donc plongé dans 'L'Entreprise du Virus' un nom digne de 1984 : 'Le Ministère des Virus et de la Régulation Démographique' Ça nous fait un superbe acronyme : MVRD. J'aurais pu rajouter 'Et de la Santé Publique' on tape dans du très haut niveau là : MVRDESP aussi… Les Humains sont tellement fragiles, protégeons-les ! La plus grande menace pour l'Homme étant l'Homme, faites une bonne action : jouez à ce jeu !
+
+Plague inc est donc un jeu de stratégie où le but est de réduire l'humanité à néant… Simple ? Non ! Il vous faudra manipuler avec dextérité et prudence un virus pour anéantir des humains qui ne sont pas super collaboratifs… Pire, ces petits rigolos veulent sauver leurs peaux et recherchent activement un remède à ce mystérieux virus inconnu…
+
+## Contrôles
+
+Lancez le jeu,  et pressez n'importe quelle touche pour passer l'écran principal. Une fois sur l'écran représentant la Terre, plusieurs choix s'offrent à vous : 
+  - [OPTN] permet d'afficher / cacher la barre en dessous du monde qui vous affiche vos points ADN et la barre de recherche des humains.
+  - [VARS] permet de passer au gros du jeu : les mutations. Ce menu vous affiche vos points ADN, mais aussi les mutations sélectionnées ainsi que vos point de contagion, de sévérité, et de létalité. Dans ce menu, vous pouvez modifier tout cela.
+  - [x^2] permet d'accéder  au menu statistique qui vous affiche les stats sur les humains. La barre symbolise la popuation totale : donc la somme de toute les barre doit donné une seule barre entière.
+
+De manière générale, si vous êtes perdu, [EXIT] vous ramènera toujours sur la mappemonde.
+
+Dans le menu des mutations, vous pouvez modifier vos caractéristiques via les touches F1 à F6 comme suit : 
+ - [F1] sert à changer les symptômes de votre maladie
+ - [F3] sert à changer les capacités d'adaptation de votre maladie
+ - [F5] sert à modifier les moyens de transmission de votre maladie
+ - [F6] sert à revenir au menu principal avec la mappemonde
+
+## Mutations
+
+Dans ce jeu, vous aurez  le choix entre plusieurs mutations pour faire le plus de dégât possible parmis les humains ! Comme dans le jeu d'origine, celles-ci sont divisées en 3 catégories : Symptômes, Capacités, et Transmissions.
+
+Toutes les mutations ont plusieurs spécificités :
+ - Contagion qui détermine la proportion de personnes infectées
+ - Sévérité touche la recherche, on peut la comprendre de la manière suivante : si la sévérité est élevée, la maladie est grave, elle entraine par conséquent une recherche active de la part des Humains. Néanmoins, votre compteur de points ADN, augmente plus vite…
+ - Létalité détermine le taux de mortalité parmi les infectés… Une létalité élevée fera de votre maladie une veritable machine à tuer, mais cela vous dévoile au grand jour et accèlere la recherche !
+ - ADN, du nom de la molècule qui compose le code génétique. Ici, rien à voir, les points ADN vous permettent d'acheter des mutations.
+ - Changement : certaines mutations par leur nature ralentissent la recherche, c'est ce ralentissement qui est symbolysé par changement. Concrétement, plus une maladie a de *changement* plus elle ralentit la recherche…
+
+### Symptômes
+
+Comme son nom l'indique, votre maladie aussi puissante soit-elle n'est pas invisible : elle présente certains symptômes qui ont leurs spécificités. Bien entendu, les symptômes présentés dans ce jeu font partie du jeu d'origines et leurs spécificités sont proches.
+
+|Nom|Coût ADN|Pt de contagion|Pt de sévérité|Pt de létalité|Changement|
+|:---:|:---:|:---:|:---:|:---:|:---:|
+|nausée|2|1|1|0|0,5
+|vomissement|4|3|2|0|0,5
+|tumeurs|15|4|2|5|1
+|pneumonie|4|2|2|0|0,5
+|toux|3|2|1|0|0,5
+|arrêt total des organes|30|0|20|25|2
+|folie|20|6|15|0|2
+|paranoïa|5|0|4|0|1
+|lésions|10|5|4|0|0,5
+|hémorragie|20|5|15|15|0,5
+|plaies|3|2|1|0|0,5
+|infections|17|6|7|6|0,5
+|immunodéficience|12|2|6|4|1
+|inflammation|5|2|2|2|0,5
+
+### Capacités
+
+En mutant, votre maladie peut acquérir des capacités. Ces capacités lui permettent de mieux apréhender un milieu ou une situation, ainsi la capacité *Résistance au froid* donne un suplément de vigueur à votre virus dans les pays froid. Cela se traduit par une augmentation plus ou moins forte de la contagion dans ces régions du monde…
+
+|Nom|Pt de contagion|Pt de sévérité|Pt de létalité|Coût ADN|
+|:---:|:---:|:---:|:---:|:---:|
+|résistance au froid|+4|||10
+|résistance au chand|+7|||15
+|résistance à l'environnement|+10|||30
+|résistance aux médicaments||+2|+0,5|15
+|résistance génétique||+5|+1|25
+|mutation accélérée||+8|+2|30
+
+### Moyens de transmissions
+
+Votre maladie aura tout le loisir de changer ses moyens de transmission ! Plus ou moins efficaces ceux-ci permettent à votre maladie d'accéder à des caractérestiques intéressantes qui lui permettront de coloniser le monde entier ! ;)
