Because of the Playstation Network's recent hack-attack and three week shut down of the network, they're offering free game downloads. I've downloaded Dead Nation, and it's a fun, old-school arcade style shooter. I call it "arcade style" because it uses the isometric camera angle, and you work your way through progressively more difficult levels while upgrading weapons and armor.

1 or 2 player, with the option of online co-op games. I haven't played online yet because I tend to play through campaigns first, but I'm looking forward to replaying levels with someone else.

If you've got some spare time and a PS3, get this game for free while you can. Pick up Infamous for free too while you're at it.
