This is a pure 3D shooter game.
Play the hero Tommy. He is a cheereoke Indian named Domasi Tawodi.
He lives in a reservation with his coming girlfriend Jen and his grandfather Enisi.
When aliens capture them, Tommy must fight the aliens to search for his beloved Jen.
PROS:
A story filled with science fiction. It draws out how humanity must overcome a great evil from the distant space.
New elements included are deathwalk, spirit mode and wallwalking. These make Prey a new experience for all 3D shooter fans.
CONS:
I think the graphic engine is a bit dark rendered.
The Half Life engine is in my opinion more 'life alike'.
