Take on the role of David Walker, a U.S. astronaut who is on a routine mission to the moon, until disaster strikes. In an instant, both the command module and landing modules are destroyed, taking the entire crew down, except Walker. When he finally awakes from the lunar disaster, Walker realizes that he has been abducted by aliens and is now held hostage in a secret world. The aliens have deemed him as the chosen one to carry out an ancient alien legacy of universal domination.

In The Ward, players are challenged to take on three different roles in order to complete the mission. First, as a fugitive on the alien spaceship, Walker must figure out why he is there and how to escape. Second, as an investigator, the mystery of the aliens and their intentions must be unearthed. And finally, as a saboteur working for mankind, Walker must stop the aliens from destroying the world.
