Infamous: First Light, a standalone expansion for March’s PlayStation 4 title Infamous: Second Son, launches tomorrow. But what’s it all about? To get some answers, we spoke with game director Nate Fox. In our interview, he explains how main character Fetch plays differently than Delsin from the original game, how long you can expect it to take you to finish, what its Battle Arenas encompass, and more.

Check out our conversation below, and look for our review of Infamous: First Light later this week.

GameSpot: What was the inspiration to make First Light? Was this planned before Second Son was released or was it in response to the positive feedback around Fetch after the game shipped?

Nate Fox: When Second Son shipped we were excited to see that players got so emotionally invested in Fetch. Her conflicted history and overall attitude made her the perfect fit for a standalone game.

What kind of tone is First Light going for? How does it vary from the main game?

First Light is pretty darn dark. Fetch’s life on the streets was tough, her time in Curdun Cay being trained as an assassin was equally rough. Through it all she’s still Fetch, no one can keep her down, but she has to fight her way out of some harsh situations.

“We definitely wanted Fetch to play very differently from Delsin with neon powers. Her abilities allow players to move faster and in a more fluid way than we’ve ever been able to pull off at Sucker Punch” — Nate Fox

Fetch’s movement in First Light is faster and more melee focused; was this intentional…to shake things up so significantly and let people play in a different way than the main game?

We definitely wanted Fetch to play very differently from Delsin with neon powers. Her abilities allow players to move faster and in a more fluid way than we’ve ever been able to pull off at Sucker Punch.

What bonus content can I expect if I already own Infamous: Second Son?

As a bonus for people who have a copy of Second Son, they can import Delsin into First Light’s Battle Arenas.

How many hours of playable content can we expect from First Light?

Don’t be fooled by the $14.99 price tag; there’s a lot here to discover. The campaign is about 4 to 5 hours long, but afterwards we unlock some new abilities and challenges for the player to achieve in the Battle Arenas.

Were you able to reach the same graphical benchmarks (1080p/60fps) for First Light?

First Light runs at the same speed as Second Son.

What sort of things can we expect from the Arena?

Curdun Cay’s Battle Arenas are extreme combat spaces where we push players to the limit. It’s pretty intense; we even score your performance. These scores are posted on a leaderboard so all your friends can see who is the best Conduit killer.

First Light is now your second standalone expansion, following Festival of Blood for Infamous 2. Why is Sucker Punch so enamored with this model instead of the traditional route of just releasing more content for the main game?

Having a standalone game means being able to create a full narrative experience for everyone, not just returning players. This lets us spread our wings creatively, making an impactful story where no one is missing out.

Is it possible we’ll see more standalone expansions based on the other conduits we saw in Second Son?

Right now we’re catching our breath after finishing First Light. But if people really dig Fetch’s story, who knows?
