Online multiplayer demos for Aliens vs. Predator and Battlefield: Bad Company 2 await you on the PlayStation Store today. They're both free, so there's no reason not to give these two newcomers a spin.

There's also a free sampler for brilliantly inventive PSP game Half-Minute Hero. Do try it, our review will explain why.

Today's other big arrival is Final Fantasy VIII, which is meant for PSP but can also be played on PS3. And this costs eight pounds, conveniently.

The rest you'll find below.
