Nate
Background
Nathan "Nate" Walker is a mission commander for NASA in Cape Canaveral, Florida. He is in a relationship with Nate's Girlfriend and was previously married to Beverly.
During the events of Apollo 18 (2011) played by Lloyd Owen
Nate is interviewed before the mission and he talks about the training given to them by Lab Tech 1 and Lab Tech 2. The mission lifts off and then Nate and Ben Anderson head to the moon in their lander while John Grey stays behind in their spaceship. Nate and Ben pull out their gear, which includes video cameras and large amount of film stock. Ben plants the American flag on their landing site and Nate takes a photo of him standing and saluting near the flag. They place motion tracker equipment nearby and a MESA unit. There is a sudden power surge accompanied by a weird chittering noise. They place the units given to them by the Department of Defense or PSD5's nearby. Ben finds what appears to be a rock near an impact crater and brings it back to the lander. Mission Control congratulates them on their first day and Ben and Nate go to sleep. During the night, Nate and Ben hear a rattling noise outside the lander. They hear a wailing sound from the communication system, but can't figure out what it is. John notifies Nate and Ben that the spaceship will be going on the opposite side of the moon and so they will lose communication with him for some time. Ben notices one of his rock samples is on the ground, but neither he or Nate know how it got out of the bag Ben put it in. They place more PSD5 units and Ben notices footprints in the ground. They try to contact Mission Control, but can't reach anyone. They follow the footprints which go around in a circle and then into a crater where they find a Soviet lander. Nate goes inside the lander, but no one is inside. He investigates further and finds blood everywhere. Ben goes to look for the cosmonauts and enters a crater where he finds the mummified body of a cosmonaut. He brings the cosmonaut's body out of the crater and notices a rip in the cosmonaut's suit. When he sticks his hand inside the rip, something moves inside and he finds a rock.
Nate calls Mission Control and tells them what they found. He asks Mission Control if they knew that the Soviets had already landed on the moon, but Mission Control refuses to admit they knew. During the night there is more static interference and Nate is woken up by the cosmonaut's helmet, which they brought back, falling on him. In the morning, Ben notices the American flag they placed is gone. Nate contacts Mission Control and tells them the flag is gone. Ben thinks maybe there is another cosmonaut, but John doesn't think so. The Deputy Security of Defense tells them they knew the Soviets had landed on the moon, and they think there is only one cosmonaut and their mission is complete. As Ben and Nate are about to return to the spaceship, something goes wrong with the lander. They try to contact John, but cannot reach him or Mission Control. Nate goes outside and records the damage to the lander and sees tracks in the ground. Nate tells Ben the tracks aren't human and finds the American flag torn to pieces. After Nate puts the rover back upright, he feels something moving in his suit. Ben goes to help Nate and finds him collapsed on the ground. He brings him inside the lander and when Nate wakes up he tells Ben he doesn't remember what happened.
Ben notices Nate is bleeding and they find a large gash in his chest. Ben feels something hard near Nate's wound and pulls out what appears to be a rock. Nate crushes the rock with a hammer and Ben thinks the PSD5's are blocking their communication and are putting out a signal to attract Lunar Creatures. Nate and Ben go out to destroy the PSD5's and find one of them destroyed and surrounded by tracks. When they return to the lander, Nate has a large infection spreading from his wound. Nate tells Ben that he is getting worse from the infection and he has to leave him, but Ben refuses. Nate quickly starts to become unhinged and starts destroying the lander. Ben and Nate abandon the lander and take the rover towards the Soviet lander. Nate causes the rover to crash and then runs away. Ben finds Nate who tells him to stay away. Nate is pulled into the crater where the cosmonaut's body was found. Ben starts up the Soviet lander and as he is about to take off, Nate bangs on the window and tells Ben to let him in. Ben refuses and Nate tries to break in with a hammer, but is killed by the Lunar Creatures.
