Season 9 and later missions has not been released yet, but is supposed to consist of the following missions:
SRM 09-01 Started from the Bottom When you are new to the shadows of Neo Tokyo, without much in the way of reputation or established contacts, the work that comes your way feels beneath your talent. But this is Neo-Tokyo and you start from the bottom.
SRM 09-02 Finder's Keepers Paranoia is a survival trait in the Shadows, chummer, but you never had a job like this one. Stay frosty, use your wits, and you may come out a bit richer.
SRM 09-03 Learning Little from Victory One thing is certain, politics is dirty biz no matter the Sprawl. Gotta love when Tanaka-san wants to keep his hands clean at your expense.
SRM 09-04 Neo-Tokyo Drift Fast and furious street racing brings in the Nuyen, and of course the Yakuza control the scene. When you get hired to monkey wrench things hit the guard rail.
SRM 09-05 Violent Shadows Tanaka-san needs an inconspicuous crew to rescue a missing child, but his Yakuza rivals are already a step ahead. Do you rescue the child for Tanaka or will you turn him over to the rival faction?
SRM 09-06 Seven Breaths War in the streets is threatening to boil over when an opportunity arises to bring it back to a simmer. Pick your preferred losers but don’t take too long as time is short.
SRM 10-01 Death's Daily Business Now that you've proven yourself in the streets, a corporation comes calling when one of their own gets assassinated. Can you handle moving up in the shadows of Neo-Tokyo?
SRM 10-02 One Stone: Two Birds Yamatetsu became Evo twenty years ago, but the old guard continues to resist Evo-culture. To encourage a return to the fold, Evo sets up an old Yakuza trick, employing your team to make it happen.
SRM 10-03 When the Bough Breaks An emergency job screams big money - and big problems. You're left holding the package and it's you in the crosshairs. Can you find the right formula to earn that paycheck with your skin intact?
SRM 10-04 Get Bento They say your soul is who you are on a bad day. For Sora Suzuki that was yesterday. Today he gets even.
SRM 10-05 Out of Body Experience A recently extracted software engineer left something behind. He wants to hire you to retrieve it. It's his wife.
SRM 10-06 Where the Wild Roses Grow When the runners are hired to fake a celebrity's death, they might find out just how deep the rabbit hole goes.
SRM 2081-01 Death of a Fixer If a runner gets geeked, it’s just biz. But when it’s a popular fixer, everyone wants to know why.
SRM 2081-02 Urgent Care With Mr. Johnson’s reputation on the line, runners must infiltrate DocWagon to extract one of their own.
SRM 2081-03 Johnson and Johnson Johnson has the job; Johnson wants the data. Too bad they’re different people.
SRM 2081-04 Trailblazers Seattle’s Underground changes constantly. As smugglers vanish along a new route, tunnel rats are called in to smoke the trouble out. An official Missions organized play event. Pre-gens available. Beginner and experienced players welcome.
SRM 2081-05 This is Renton When the neighborhood watch is in cahoots with a murderous thrill gang, the obvious course of action is to throw a party… with bullets.
