| Discovery of Draculin, a glycoprotein found in vampire bat saliva that works by inhibiting specific coagulation factors in blood. |
| First scientific studies done on Draculin using animal testing. |
| Draculin first tested on humans in a scientific study. It's found that the drug is not only safe, but patients also tolerate it. |
| Tests bought out by the scientific corporation Cypher. They announce their intentions to have a new drug ready for Phase I testing by 2010. |
| Phase I trials of using Draculin to help prevent strokes rolled out. 2 weeks later, test subjects begin to show worrying signs of genetic mutation. |
| Start of the virus outbreak. |
| The world begins to shut down, but it's already too late. The infection's already spread across the globe, and society begins to crumble one city at a time. |
| The virus is officially given the name DraC-2. |
| The Military takes control of a city to set up a quarantine zone, overthrowing the current government and police force. It's given the nickname Stronghold. |
| The internet disappears, and Stronghold is cut off from the rest of the world. |
| Stronghold is officially declared the last remaining city in western North America, and the Military begins construction to build it into a massive quarantine city. |
| First relays installed for a new, Military-operated communication system. First devices are given out to Militay personnel only. |
| Cypher begins ground-breaking research on the virus. The Infected are catogorized into two different levels: Level I Newborn and Level II Hunter. |
| First evidence of the virus being able to mutate upon discovery of a new level of Infected. This level is given the name Level III Feral. |
| Infected nests become known. |
| The Military creates its Task Force Branch to begin systematically hunting down Infected nests and destroying them. |
| Communication relays open for public use. |
| First discovery of a new specimen, later given the name Level IV Reaper. |
| Jabberwockies are formed as the first officially recognized threat towards the Military. |
| The scientific corporation Cypher given full reigns on Infected study; all other science labs are mysteriously shut down or abandoned. |
| Eclipse formed, the second officially recognized threat towards the Military. Their homebase, the Junkyard, is the first fortified human encampment besides Stronghold since the outbreak. |
| First discovery of yet another new specimen after 40 years. The science community realizes the infection has once again taken on a new mutated form, and calls this new Infected by the name Level V Patient Zero. |
| Current date upon site's opening. |
| Cypher hosted an exclusive event to show off their latest experiement: Project X. The unveiling became a disaster when the new, highly mutated form of Infected suddenly broke free, escaping somewhere into the rest of Stronghold. |
