Amazon keys on Steam - at all?

Games bought from Amazon are only able to be activated on Steam if they use Steamworks as DRM, as far as I know. There are some exceptions though.

Amazon has been getting way better about putting whether a game activates on Steam.
If you bought the Square-Enix pack this week, Underworld is the one game that does not activate on Steam.
Almost all of them will say if they require Steam way down at the bottom of the whole description.

You have to read carefully. For some games they even have both a Steam and non-Steam version like Bioshock.
Steam version
Non-Steam version

Some game downloads that you buy from Amazon aren't Steam keys, but are product codes used to activate the game when you first start it up, which are usually SecuROM codes. Some, but rarely, are Origin keys. You'll only get Steam keys for games that say it uses Steamworks on the game's info page. I've bought a lot of game downloads from Amazon.

"activatable" is a perfectly cromulent word. Learn them to embiggen your vocabulary.

I remember when I had to swap a dozen 5&1/4 inch diskettes between one or two floppy drives to play a game I bought.
Will accept taking the time to figure out where I download my game from any day of the week.

does Wings of Prey redeem on steam?

I have bought multiple games off of amazon but yea only some actually activate on steam

some on steam some on origin it all depends.

I ordered a black power fist afro pick. Don't fail me, Amazon.
