100%'d this bad boy a little while ago and really enjoyed it. It warms my heart to see developers pack tons of new content in stand-alone downloadable titles; there are so many new assets, new music, everything!
There are some surprisingly good UGC missions to be found too, if you have the patience to sort through all the EASY TROPHY!!!!!11 ones. All in all, great value for its price.
Sucker Punch have something really sweet going on with this franchise, I just love their style. Congrats to them for making the fastest selling PSN game in history, well deserved.
EDIT: Man, I'm just now realizing how much I'll miss Shadow Swarm when I get back to replaying inFamous 2. Such a painless
and badass way to traverse the city.
