At what chapter does Extra Mode become playable?
Once you finish Chapter 4 it becomes avaible.
Note that if you jump straight into Extra Mode after chapter 4 there will be a lot of stuff missing - you don't unlock everything in Extra Mode until you beat the Story.
It's still worth checking out though. Trying things from a different character's perspective, and trying to get those valueable S Ranks on the missions.
You could but you won't be able to by very good weapons untill you get farther in story.
What exactly is the Extra mode in PSU?? Do you just replay missions as your own character?
also....
Quote: Playing by yourself? Need help? Make sure it's got something to do with PSU aswell please!
Did anyone else think this was a Double Entandré. Or was it just me
extra mode in PSU, is like online PSU with story characters taking place of the online humans.
Yep and it revovles around story mode. So whatever you unlock in story mode is unlocked in extra mode.
how many playtime hours is in story mode ?
It took me just over 23 hours myself... that was with little to no extra training. Plenty of exploring though.
