@Spud, your idea is fine.
With that said to all, there will be a cap on Govvies unless more Greasers and Survivors are put into the game.
@NuttsnBolts, the game will probably not have Screechers but will definitely have Fatties. In order to kill a Lurker, the destruction of the brain will be in order. Even decapitating a Lurker's head will not result in its death--much like that of a snake, a Lurker can still bite. The 'infection' highly exacerbates the hypothalamus' control of the host and causes it to solely want to devour any living thing, preferably human as the 'infection' is a creature that survives mostly on humans (animals are a lesser option on the dominance hierarchy) while also seeing humans as its biggest threat. The thalamus will also be damaged in regards to the Lurkers' abilities to feel pain. As to not turn this into a Master Thesis, I'll sum up the 'infection's' impact on the cerebrum as the Lurkers are either on a stand still or in a hyperarousal fighting stage, which coincidentally causes them to be sensitive to smell and light and more prone to roam post sunset. However, there are stages of the 'infection,' which shall be made clearer in the IC Thread (unless otherwise requested by any players prior to the making of the IC Thread); Lurkers were more prone to attack during daylight when the outbreak first occurred. However, as this may seem more convenient later down the road in regards to hunting during the day time, the Lurkers can and will still attack when light is out. As well, the more the 'infection' takes over a host, the harder and more dangerous it is to kill a Lurker.
The intelligence of Lurkers will not be extreme. Lurkers will probably not be able to use basic tools. Short term memory will be minimum and mostly used to fulfill the desires of the hypothalamus. Long term memory is attainable in regards to staying in one roaming area. Emotions and coherent speech will be close to
nihil (which leaves little room for creativity). As a host is infected, the intelligence begins dropping, but while the motor skills will be skewed, they will be stronger and faster due to the ability to move through pain.
The 'infection' spread globally (although, the rumor is that the 'infection' started in America), and many nations have isolated themselves. Since many countries relied on each other for certain imports, the outlook on the global economy is not doing so well. Some European countries may still be trading, but as far as America is concerned, the nation has isolated itself entirely, and communication is unreliable and minimum, especially on an international level.
The terrain in Zone B is going to be better than most of the other factions; however, Zone B is still in pretty poor shape. Each state in Zone B has several Safety Shelters set-up, which are communities or compounds for the few people who made it past the clearances 'in-time'. Each Safety Shelter has a large concrete wall around it in order to protect what remains of the American society from Lurkers (and Greasers). The resources inside and outside of the Safety Shelters are pretty minimal due to the military having bombed many inhabited places as a last resort to destroy the Lurkers. It is possible to live off of the land, but it is hard. Many Greaser groups have taken to using abandoned military bunkers, but not all have. There are Greaser groups who are allies, and there are Greaser groups who are enemies. It is not uncommon for Greasers to pillage the Safety Shelter transportation vehicles that are trading imports and exports from other Safety Shelters and factions. With that last bit said, the government is beginning to take heavier action against the Greasers as resources are running drier.
