Headlining this week's PSN update is OlliOlli, the tricksy skateboarding sim from Roll7. The Vita game is the one new release proper - flip to our four-star review for the lowdown.

Staying on wheels, Grid 2 gets a DLC-stuffed Reloaded edition that bundles in two circuits and 25 cars. If you'd prefer something more on foot, PSOne slice-em-up Lucifer Ring is waiting in the wings; its arrival on PSN is the first time it's been released outside of Japan.

Outside of releases, Joystiq Top 10 of 2013 entry Brothers: A Tale of Two Sons is free now to Plus subscribers. The puzzle-platformer is joined in the Instant Game Collection by Worms: Battle Island on Vita. There are also demos of Lightning Returns and Toukiden: The Age of Demons to check out.
