Not your cup of tea? Maybe The Crew is more your speed? You can pre-order for a closed beta key, as well as picking up some discounts if you pre-order through GMG or GameFly. That beta starts up on August 25th. Rising Generals also hit closed beta testing, so if you'd prefer to take a more strategic approach to your combat, that's an option.
Wait, none of that is what you're looking for? Huh. Well, then, maybe you should just jump on past the cut into our full list of betas, where you can find several other options. As always, if something's missed our notice, let us know in the comments!
