Welcome back to Seattle, or at least 50% of it. The origin story of Abigail Walker aka Fetch is a gloomy one. Set two years before the incidents involving Delsin, she and her brother Brent gets in all kinds of trouble leading up to her confinement in the hands of DUP lead by Augestine. The story is told in the form of flashbacks intertwined with arena matches to present new powers as you go along. I particularly enjoyed the last part of it.
pro
While they did cut your playground in half, Seattle is still a pretty place to hang out it, and there is no better way to present that by mixing in Fetch' neon-tastic abilities. With new powers including a new super move, you are more than ready to face off against your new enemy and the DUP. The way Fetch pulls off her super move shows how cool a character she is. A new but trimmed skill three provides a new twist to familiar abilities. In terms of graphics and sound there's little to complain about, and the facial animations are up there with the best.
pro
Most of the new side activities are variations on the old ones, and they are welcome as something to do in between missions or as a way to gain points for upgrading. Neon graffiti, saving hostages and stopping drive-by's are some of the ways to pass that extra time. An arena mode is also available which can provide a couple of hours of extra fun if you're into leaderboards and score chasing.
con
I'm not sure Fetch is a solid enough character to hold a story of her own, such as this DLC. For most part the story made me feel completely indifferent about Fetch and her brother, and it wasn't until the very end that things got noticeably darker and much more interesting. If only this was where the game started and built from, it could have been a different kind of beast. Everything before the end is actually kind of boring.
con
First Light, like Second Son, suffers from side activities that aren't very interesting. Additionally there's not a lot of them in this DLC, which might be considered a blessing or a curse depending on where you stand. On one hand they're not very fun, so having just a few makes it easy to get them out of the way. On the other hand you're done exploring the city for things to do rather fast.
con
To unlock and upgrade every power you're pretty much forced to play the arena mode. If this isn't your cup of tea, well, tough luck. There are challenges you can do in the main game that will give you points, but you'll still be missing 88 points when you're done. Forcing on a mode like this to see everything the character is capable feels cheap.
