EA and Visceral Games have opened up beta access for Battlefield Hardline on PC. If you aren't already participating, you can now get in immediately by signing up here.
Having only played a tiny bit of Hardline so far, I get the impression that this will be enough for me -- that I'll get what I need out of the beta, freeing me up to wait until the full game is on sale.
Even with the change in theme and setting, it's still very much Battlefield. I'm curious to see what all will make it into the final package to justify the full $59.99 price tag.
