I don't know, why *isn't* Prey on here.

Used to be. You can register retail keys as far as I recall.

It's a 3dRealms game... And properbly Held the "record" of Vaporware to release for a long while.. Until DNF was released.. At the moment You'll need to Contact Besesada/ZeniMax. (They bought the rights to the games.)

You can buy Prey from stores such as amazon and use the retail keys which will register on steam, that's how I got Prey.

prey was bought by another company. and i think sometimes went wrong with continued distrabution.

Steam ran out of keys. If you want Prey, buy it retail (unopened) and add activate it through Steam

Aye,Prey:)
