I've been playing the beta here and there when I have time. It's my first time playing a SOCOM game, but I think it's fun, and possibly even better if you're playing with a bunch of people you know. It's a beta, so don't expect the game to run perfectly right now, the only annoying hiccup the game suffers is when it's loading the match (when the match is reset) and it takes a few minutes sometimes, but they're fixing as we speak it so it's all good.
Silks, pay attention to your PM box because I will send my beta promotion code that I can share with 2 other people.
