It's the last PSN store update before Christmas. And, oh boy, it's a biggun.

There's some really excellent downloadable stuff popping up on PS Vita this week. Basically, have your credit card at the ready.

If only you could bundle digital downloads into Christmas stockings, huh? That'd be a pretty easy way to get a whole bunch of Christmas present purchases out of the way.

Let's see what we've got, then...

Full-price releases

Bit.Trip Runner 2: Future Legend of Rhythm Alien was released for other platforms earlier this year, and has finally made it to PS Vita.

It's well worth checking out this most difficult of rhythm-runners, in which you tap buttons to the beat to guide your hero over and under obstacles.

It costs just £5.49 / $9.99, by the way, which is a bit of a bargain.

The first episode of Broken Sword reboot The Serpent's Curse is also now available for Vita for £9.99. Although if you're a PS Plus subscriber, you can grab it for 20 percent off.

And Eufloria finally makes its way over to the Vita repackaged as Eufloria HD. It's a strategy game about sending seeds to conquer planets, and it's pretty gorgeous. £7.99 / $9.99 for that, or £6.79 / $7.99 with a PS Plus subscription.

There's also Age of Zombies for £3.99, the A-Men 1+2 Bundle Pack for £9.99, Backgammon Blitz for £4.99, the Indie Hits Bundle for £3.19, MotoGP 13 Compact for £7.99, and The Ultimate Foosball Bundle for £2.39.

Meanwhile, Americans can download Terraria for $14.99, the wonderful Mutant Mudds Deluxe for $9.99, Furmins for $5.99, and Sparkle for $5.99.

Phewww!

Sales, price drops, and PS Plus

DLC for PlayStation All-Stars Battle Royale is going cheap this week.

Over on the US store, meanwhile, you can pick up a whole bunch of games on the cheap, like Atomic Ninjas, Limbo, and Guacamelee!

And if you're a PS Plus subscriber, you'll find that there are tons more discounts available, including on games like Lego Marvel Super Heroes, Terraria, and Foosball 2012.

PlayStation Mobile releases

Two new PS Mobile games this week.

UFO Dad is a mash-up of a match-three game and a classic platformer. It costs £3.39.

And Night Riders looks a bit like the classic Super Hang-On, albeit with worse graphics. That's £1.39.

Have a good Christmas!
