Can We Publish FPS Creator Games in Steam?

[C]

I have created a game in FPS Creator(Classic) and want to publish it in steam. Is it possible? I've seen that we need to add steam sdk in order to publish but FPSC (as far as I know) has no such facility. after contacting FPSC support, they were like yes it is possible but we don't support thirdparty sdk. contact steam for more help.

These could help you get started.

EDIT

Not sure how much the Classic differs from the Reloaded, but on the latter it's definitely possible:

With GameGuru you can make a multiplayer game in a few minutes, including hosting and sharing your game online via Steam Multiplayer!

Using the Steamworks SDK isn't required, it's just recommended because you'll probably want to include some Steamworks features in your game.

I'm pretty sure to an extent it's required, if you read the Partner -website.

Do correct me if I'm wrong though.

EDIT: I guess I'm wrong, I just compared the Steamworks SDK Redistributables between Left 4 Dead and something obviously not Steamworks like Far Cry 3. The latter didn't have the .dll -files the former did.
