asian story starts in the dojo
dunno bout cartel

You have to complete the triad questline to unlock the cartel questline. Exit and re enter your apartment, you'll get a phone call asking for your services.

there's definitely a questline with the zaibatsu, and there's something else to do with HEAD radio being taken over
anybody got info on that?

The only thing so far about Zaibatsu is the last radio mission and one part of Cartel's story.
I wonder if the thing about red hook have a continuation or is it a bit of reference to other story...

Yup, go to the alley next to the triangle club and go to the radio. You'll have to jump over a fence. Then just do what the radio says and you'll unlock both missions!

Also, the red hook thing doesn't really go anywhere, you just do a job for the guy and then nothing really happens I guess?

Vigilante quest ends with a Ziabastu shooter giving you fear, radio jsut says BOL for the shooter and I think thats it,

Yeah, I noclipped around, we've pretty much discovered everything.

There is a fight club and an area where you have to find three buttons and then someone tries to kill you, but those are mostly just easter eggs without any significance, I think.

can anyone tell me all available questlines to do in 1 go ?

i have triads->cartel->radio missions

anything more?

Sicilians are at cafe baltic

Uhhh, not that i know of. Though if you read the ipad downstairs in the triad base you can sell drugs

Alright here is what i found out. As someone said in here there is a SAW like ''game'' room in a back alley, you can find the alley at apartment 44.

There is also a cybercafe right in front of apartment 22, it will have a sign that says it. Which is literally right beside the shops near spawn.

There is a place where you can bet money in an alley besides Lucky Pawn where the homeless have shelter (You can buy ammo in Lucky Pawn), it will have a light right outside of the door.

There is a radio you can answer in an alley right beside ''The Triangle club'' which personally i loved.

there are drug dealers around the city.

-Stiggy, hangs around Chinatown in an alley, sells weed, morphine, and downers, buys coke and acid.

-Han, apartment 22 (near rice&fins) sells heroin, coke, buys ecstasy and downers.

-Danny apartment 44 (near diordna hotel). Sells ecstasy and acid, buys weed and heroin.
Keep in mind there is a note pad in the dojo where you can find this in the room right infront of you when you walk in, and maybe others around the map.

There is an Abandoned Orphanage where you will get invited in by people with baseball bats, and after you kill them there will be a journal saying the backstory of the orphanage.

On top of VEIKKO (Right infront of Cafe Baltic) on the roof there will be the infamous ''MAP BY CHILL'' there will be a cube on top of there, if you press it you will get 5 Currency.

*MAIN MISSIONS* Alright the ones that i know of is. In Hyaku Dojo ( infront of terminal hotel ) where you will fight and then get a mission, if you survive of course. Other one is in Cafe Baltic. After you finish one of these you will get a room where you will get a phone call for an extra mission if you want one. Alright that's all i could think of for now but i will post more when i find some!
