Do I have Playstation Plus for free at the moment?

I don't really see the appeal of playing an Uncharted multiplayer. Same thing with games like Bioshock.

I feel there are games with better shooting mechanics in general... and just better suited for multiplayer.

I wasn't a big fan of Uncharted's multiplayer, but Bioshock 2's really hooked me. I liked that there was the whole "power in one hand + weapon in the other" setup, it's quite unique. Being able to set traps (great in capture the flag), stealthily paralyzing your enemies before blasting them, hacking turrets to assist you. I really enjoyed it.

I'm getting the unavailable msg again:

PlayStation Network is not available at present. This could be for a number of reasons including scheduled maintenance or essential updates and we apologise for the inconvenience caused. In the meantime, you can continue to explore the world of PlayStation at eu.playstation.com.

I play Uncharted 2's multiplayer fairly often. All the co-op stuff is fantastic, so I'm very much looking forward to what Uncharted 3 offers.
