Vulture Valley

Vulture Valley is a valley north of the DMZ zone in Vietnam. The valley was used as a testing site for the USSR's particle colliders, but a mistake caused it to create a wormhole and release multiple prehistoric animals into the valley, destroying much of the native wildlife. General Amadeus Jericho would discover this operation during the construction of the second collider, and built his his own base in a southern corner of the valley. Jericho, with the help of Vulture Squad and the native Tyrannosaurus pair, would destroy the Russian presence within the valley and build a perimeter wall to contain the dinosaurs that had remained in the valley.

Description
Vulture Valley is a large jungle valley found in the north of Vietnam, running from a single opening in the south for miles north. A perimeter wall spans this opening, built by the USA in order to keep the wildlife within the valley. On the most South West end of the valley, Jericho's Base sits on a hill overlooking the jungles. A water fall at the northernmost tip of the valley creates a river which runs south through the entirety of the valley and out the southern entrance. As the river gets closer to this exit, it branches off into multiple smaller rivers and streams to create a floodsplain, with less trees than the surrounding jungles and is a common feeding ground for Triceratops, Parasaurolophus, and Kaprosuchus.

North of the flood plains are several research stations placed by the Russians in order to study the dinosaurs, spread out throughout the valley. A large game trail spans from the river to the western edge of the valley, with an abandoned Viet Cong Camp set up near the cliffs. This trail is a common hunting ground for the Father Tyrannosaurus. Just north of the game trail is a small forest of bamboo, where the Tyrannosaurus have created their nest. At the Northwestern-most side of the valley is a destroyed Russian Compound and an abandoned Utahraptor nesting site. On the Northeastern side of the valley is a mangrove swamp, which is constantly raided by bull Kaprosuchus and Utahraptor's before their nesting site had been abandoned.

Russian Control
At some point during the Cold War, Gigory Borodin chose the valley as a remote site for Andrei Wynn to build a particle collider for non-radioactive nuclear weapons, an d built a compound in the northwest of the valley. However, the test firing of the collider malfunctioned and created a wormhole, releasing multiple species of prehistoric animals, which destroyed much of the compound and escaped into Vulture Valley. Angered by the failure, Borodin sent Andrei and his team to construct multiple research stations in the valley and use them to study the dinosaurs, before sending soldiers to slaughter all of them except an off sight Andrei, and gave another scientist named Misha the job of creating a new collider over the next year. In this time, Borodin would mostly leave the prehistoric animals alone outside of killing 7 of the 10 known Quetzalcoatlus.

At some point, an investigation on radioactive waste being dumped by Viet Cong south of the DMZ would lead Amadeus Jericho to discover the Russian presence within the valley, with him setting up camp on a hill at its southwestern-most point. Jericho would send a platoon of Green Beret into the valley to investigate the Russians, but they would all be killed by Utahraptors. Faced with no other choice, Jericho called in and sent Vulture Squad into the valley, who would discover the dinosaurs within the valley and a surviving Andrei, who told them of the collider. Con-Nhen was sent to find what the raptors had left behind and report the American presence to Borodin, who subsequently sent The Dogs of War to capture Jericho. Although the team lost Gerald Keyes and at their rendezvous both Nguyen and Charlie Miller would be captured by Nhen's Viet-Cong, Vulture Squad would return with Andrei to Jericho's base, where the remaining of the Dogs of War (having lost two of their men to the animals in the valley) and helped fend off Sergei Medvedev and capturing Nikita. The situation over with, Vulture Squad would present that they knew of the collider being built in the valley and wanted only to find Miller and Ngueyen and then leave once Leon Varnes (who had been injured by Utahraptors) recovered. Jericho compromised by allowing them to do so before being picked up by his Black Ops and help them stop the firing of the second collider.

As the two teams and Andrei left downriver by boat, they are attacked by a pack of Kaprosuchus, who kill Logan Stovall of Vulture Squad, before reaching the game trail where what remains of Vulture Squad and Andrei head off to find the missing men while the Black Ops returned to base. Miller and Nguyen, meanwhile, take out the Viet Cong encampment with the help of a pack of Utahraptors, with Miller killing himself in order to destroy the radioactive substances with them, leaving Nguyen to return with Vulture Squad and give them a map to the Russian Compound. Back at base, Sergei returned under the cover of a pair of attacking Quetzalcoatlus, the three taking out nearly everyone in the base and allowing Sergei to free Nikita and capture Jericho, stealing the boat from the Black Ops as they check over the massacred men. The Black Ops men take The Father Vulture back to pick up Vulture Squad and using the map they head to the compound. The Dogs of War make it to the compound first, but are betrayed by Borodin, who kills Nikita. Before they can execute Sergei, one of the guards kills a Tyrannosaurus chick, and the parents quickly destroy the compound in a fit of rage. The Father Vulture would arrive after the dinosaurs had left, with Vulture Squad and their entourage searching Borodin's office while the Black Ops scouted the perimeter. The group would find and be joined by Jericho and Sergei, but the Utahraptors return, killing the Black Ops, Ryan, and Sergei as the survivors escaped into the Father Vulture and the Collider is destroyed in a large bombing which also killed much of the attacking raptors.

American Control
Once the US took control of Vulture Valley, a Perimeter Wall was erected to contain the animals and Stalker Force was formed under former Vulture Squad member Xavier Wise in order to attempt to control the spread of animals that escaped and kill the most dangerous ones still within the valley. Within the first three months, the main Utahraptor colony would escape, leaving several smaller families and a smaller colony in the valley. Stalker Force would work to eliminate these families alongside the Quetzalcoatlus, quickly succeeding in eliminating the latter species while the former species continued holding out. In their work, Stalker Force discovered a mated pair of Yutyrannus, who were also working towards eliminating the raptors, and under the constant pressure, the Utahraptor population would be brought to a few rogue families with the only major colony being completely wiped out, at the cost of several members of Stalker Force and both Yutyrannus.
