The popular gaming news website Amped DX has interviewed Insurgency, a modern infantry combat mod for Half-Life 2, with twenty in-depth questions into the mechanics and gameplay. Here is an excerpt:

We do not have any current plans to create a singleplayer component of INS. We are just concentrating on the multiplayer aspect, as creating both would be a tremendous amount of work.
