Plot:
An unheard-of burst of cosmic energy entered the earth's atmosphere in March of 2038. It struck once on all continents, though it left little trace of its presence. No one thought much about it until the second wave struck, sending waves of radiation throughout the world. Countries directly affected experienced droughts and unbearable heat, and people who had been outside during the time the wave hit had received blisters throughout their bodies. When the third wave hit, communication was lost and people began to panic. Earthquakes and other natural disasters were amplified, with scorching temperatures, and floods, destroying parts of the world.
Following this people began to act strange, many became paranoid and extremely afraid of one another, and then the physical side effects began to show. Those who had received blisters during the second wave began to experience a change, at the site of the blisters, the skin turned grey, then black. It ran through the person's veins making its way to the infected person's heart and brain. There was nothing that could be done to stop this…this...this… phase people were experiencing. Then those infected seemed to go mad, their paranoia taking over them, and letting out agonizing wails as they changed. These people were horrifying and were started to be referred to as ‘Terrors’. And the only people that were immune to this were between the ages of 16 and 20.
Of course, this left the governments scrambling, now that majority of the population could contract this virus. Weeks into the apocalypse they were able to adjust and create safe houses. An area called the Dome was constructed in Harlington Texas, an area that hardly had any affected by Terrors. It was here that people found refuge as the world seemed to collapse. Over the next year or so, other safehouses were constructed, though areas outside of the middle of the US suffered the greatest, and became uninhabitable.
The leader of the Dome has recently received news, a year into the apocalypse, that a vaccine has been made in a small town in northeast Iowa, though the lab it was in was broken into and overrun by Terrors. He has made the decision that it is time to send a group to retrieve it. People in the Dome are growing restless, trying to leave but the Leader won't let them, afraid that they are all that's left of humanity. But the Leader won't be risking his own neck to retrieve this virus. Just the lives of those immune.
7 Groups later, Delta B2 is the last hope. No other group before them has returned. The date is now May of 2040. Two years in the apocalypse.
