I'm currently working on my game, and we are planning on releasing a closed beta pretty soon. I would like to use steam to make it, as it has a key generator to give people access, but I can't figure out or find out anywhere if you need to pay for the Steamworks partner, just to make a closed beta. Thanks. (sorry if I asked wrong or something, the first question on here)
