Destiny: buy The Dark Below before January 15 to receive the Tumbler

Destiny fans, if you want the exclusive Tumbler Sparrow you need to opt-in to The Dark Below quick smart.

Destiny owners who buy The Dark Below (or the Expansion Pass bundling it with upcoming DLC pack House of Wolves) before January 15 receive the Tumbler, an exclusive ground vehicle not available through other means (yet?).

If you don't get in before this cut off date, Bungie won't be sending it to you.

The Tumbler isn't the fastest Sparrow around but it's a significant upgrade from your starting vehicle. It has a couple of advantages, too, beyond its flashy paintjob and flame trail.

As you hopefully know by now, using the emote keys while on a Sparrow makes your Guardian gesture in various directions. On the Tumbler, however, they have a second function; emote while in mid air to do a trick.

Additionally, if you hold down the right trigger while in mid-air, you can move the left analog stick to roll the vehicle in various directions. Land a trick successfully, and a soft chime will let you know the game acknowledges your badassitude.

Here's the lowdown from Bungie:

Once you acquire The Dark Below through any means, the Tumbler will be delivered to you via the Postmaster.
