In the beta you are able to play with any weapons that you had before as well as receive new weapons or old weapons with adjustments to their specs. Also there will be some tweaking of the class abilities, map changes, and other stuff that Valve has thought might be nice to add to the game itself.
I don't think I'm gonna spend much time with the beta, but I like the idea of adding new entrances/exits with granary. I'll try it out and see how many people are playing around with it. And it has official Valve beta servers
What are your thoughts on this? Maybe you've already tried it out
