[Age of DOOM] Story feature

Tutorial Campaign: Tutorial Scenario doesn't have a connection with the main Doom campaign. Because this is the special tutorial map.

• LOCATION: "World's Main Demon Invasion Base Area"
  TIME: 2148
• Demons achieved to invade the World from their Hell planet by using new open teleportation portal gates. All Human countries combined inside of the United Nations to save the World from Demon Invasion. Human Troops and Demon Troops started to fight with each other. Demons slaughtered millions of people to conquer the World. Demons wanted to make the World like their own planet the Hell. They wanted to be the only ruler of the whole universe. They wanted to colonize into all planets one by one. They wanted to make their race the king of all other races.
• After many years of war and struggle Humans achieve to learn the place of the World's main Demon teleportation portal gate. If Humans achieve to destroy this teleportation portal gate Demons won't be able to teleport into the World anymore. So all Humans will be able to kill all remaining Demon Troops of the World. Humans send their best elite soldiers to Main Demon Invasion Base Area to destroy the main Demon portal. But Demons have also their own precautions about this move. So will Humans achieve to destroy the main Demon portal of the World?..

Doom Campaign: There are 4 different scenarios (for now) that continues with a chronological order. Also all of them have a connection. Because they occur in the same universe.

• LOCATION: "The Martian Civilization Zone of The Mars"
  TIME: Ancient Times
• A "Martian Civilization" was available in the Mars planet thousands of years ago. This civilization was a very developed civilization in that timeline.

Dr. Samuel Hayden starts to experiment by using his teleportation device with his Human Subjects. He wants to open new teleportation portal gates to new unknown planets. He wants to reach new unknown planets with his portal technology. Because he wants to colonize all planets one by one. He wants to make his civilization a new "cosmic super power" by capturing all planets one by one.
• After some experiments Martian People start to protest Samuel Hayden. Because Samuel's experiments have too many risks. Some Human Subjects get lost in the new planets because they can't return to the Mars due to Samuel's teleportation mistakes. In addition Martian Civilization wastes most of its budget to these experiments. So ordinary people start to become too poor. One day Samuel and his special guards explore "The Haunted Area" in a deeper creepy part of the Mars. Samuel decides to open a new teleportation portal gate in The Haunted Area...

Humans and Demons start to interact with each other by this new teleportation portal gate.
• Demons behave very friendly to Humans in the beginning. Even Demons send their "Argent Energy" to Humans. All UAC Mars Bases start to use this super energy source for most of their process.

UAC Human Subjects, who returned from the Hell planet to the Mars planet, obtain new psychological and mental problems. Some UAC Human Subjects start to kill UAC Personels with no reason.

Our Marine has to reach "UAC Phobos Base" at first. After that he needs to join "UAC Bravo Team" in there to destroy "Phobos Teleportation Portal Gate" along with this team. Unfortunately UAC Bravo Team is down before our Marine meets with this team. So our Marine has to destroy "Phobos Teleportation Portal Gate" by being alone against lots of threats.

Because the Deimos portal gate is in "UAC Deimos Base". So Marine's UAC Marine HQ Commander Thomas Kelly tasks Marine to reach "UAC Deimos Base". They plan to meet with each other for destroying the Deimos portal together.
• Dr. Malcolm Betruger and Demons have also their own plans to stop Marine. They plan to destroy Marine's all allies one by one for making Marine alone in all UAC Mars Bases.
