The Flying Scotsman

Hello, I am really interested in this game. It reminds a lot of Planetside, an MMO. However, I do like realism in my games as well and combining futuristic combat with realism is a first, and to me, a must have. It will give me a nice change from playing WWII Online. A couple of questions. Where can I apply for the public beta? And, since you will be purchasing online, is Paypal an accepted payment option?
