There's lots of things available as part of this week's PlayStation Store update, but only one you should really care about. And it involves Mark Hamill.
It's not a Batman-related DLC pack. It's not a Darksiders demo. It's Wing Commander IV. Only downside is that it's obviously the lesser PS1 port, but hey, Wing Commanders can't be choosers.
Not much else of note available this week aside from the MAG open beta and a ton of sale content, but if you'd like to check for yourself, the full update is below.
