Arcadia

Arcadia is an Umbrella ship in Resident Evil: Afterlife

A Safe Haven
Alice, Claire, K-Mart and the rest of Claire's convoy heard transmission's back in the Nevada desert coming from Aracadia. The transmission's said that there was no infection and that there was shelter and supplies. Alice didn't go, but Claire and her convoy headed there. Believing that Arcadia was a town, they looked around for the survivors sending out the transmissions only to be confronted by Umbrella soldiers. Umbrella put the Scarab device on Claire and K-Mart. Claire broke free, but the others ended up being kidnapped.

Boarding the Arcadia
As Alice, Claire and Chris, now nowing that Arcadia is a ship as revealed by Luther West, board the ship thinking it's a haven and to search for Claire's missiong convoy. All of Claire's memory comes back to her and she tell's the other's that Arcadia is a trap. They enter a room that later turns out to be a holding area for 2,000 test subjects. They bring up the pods and find K-Mart first, Claire takes the Scarab off her chest, and then releases the others.

Alice follows a trail of blood which takes her to a new room. She finds herself confronted by Wesker and a survivor from the prison, Bennett, who has betrayed Alice. Chris and Claire sneak up behind Wesker, but he knows their there. A fight begins and Chris and Claire are trapped in pods that descend underground. As Wesker is about to ingest Alice, K-Mart enters the room, picks up one of Alice's shotguns and smacks Bennett across the face and then tosses the gun to Alice and she shoot's a hole in Wesker's head. Alice then releases Claire and Chris and they help the others escape. As Alice, Claire, Chris and K-Mart are leaving the room, Bennett is killed by Wesker. Claire then realizes that Wesker is trying to escape and Alice. Claire and Chris start shooting at his plane. Wesker tries to blow up Arcadia and then notices the the bomb was in his plane, which ends up blowing up the plane and seemingly kills him. A parachute can be seen falling as the plane blows up, so his fate is unknown

As Alice, Claire, Chris, K-Mart and the other survivors seem reliefed that everything is over, Alice decides to really send out real broad cast from Arcadia in an attempt to save other people left alive in the world.
