Christmas may be over, but Sony is continuing its festive giveaways over on PlayStation Mobile.

This time around, Rock Boshers DX and Bike Rider DX are the games that are available gratis.

When we reviewed Bike Rider DX on 3DS, it just missed out on a Pocket Gamer Award.

"If you ever see it in a sale though, and you like auto-runners, give it a shot," we said. So, it's definitely worth grabbing as a freebie.

Bosh!

Rock Boshers DX, meanwhile, is an extremely British affair made in the style of a ZX Spectrum game.

The game stars Victorian explorers who travel across Mars; bosh rocks; and rummage for tea and scones. See! I told you.

If you've got a Vita or a PlayStation Certified device, you'd better head over to the PSM marketplace now before these offers disappear.
