Here[acidpool.at] you can download a .zip with three savegames.

AWMF_0_(Get_a_lot_of_money_after_the_first_mission).sav
I found out you can edit the savegames with https://www.saveeditonline.com/. While there was no entry for money I set the highscore for the first mission so low that you get a lot of money when you finish it.
If you go for the Buy/Upgrade-achievements buy one upgrade, exit and re-enter shop and then buy the next. Sometimes the achievements won't trigger right away.
Also if you update several things at once only one of the possible tutorials will pop up. To get all of them you have to be patient and buy one after the other.

AWMF_0_(625_IDs_collected).sav
There are 627 collectable IDs in the game. With this savegame all you have to do ist start a new campaign and collect 2 more to get the Collector-achievement.
(Fyi drinks don't count.)

AWMF_0_(Get_pacifist_and_decisive_after_this_mission).sav
Getting this one was the worst... since there is no notification if you fail I had to record my gameplay and rewatch it after each mission to check if the decision timer ran out. If you load this savegame all you have to do is enter the last club, convince the four guys and leave. Since only cyberfists are equipped noone will stop you. All you have to take care is that the decision timer never runs out.
After this you'll get the Pacifist and Decisive Campaign-achievements. (I'm not sure anymore but I guess "Can’t touch this!" is also included...)

The savegames fo All Walls Must Fall (AWMF) are located in C:\Users\xyz\AppData\Local\ProjectDisco\Saved\SaveGames
All you have to do is delete/backup the "AWMF_0.sav" and the "steam_autocloud.vdf".
Then rename the savgame you want to use into "AWMF_0.sav" and start the game.
If Steam asks which file you want to use (the newer one in the cloud or the older one on your drive) choose the one on the drive.

Oh, I forgot. I played the game in german. To change the language enter "[OPTIONEN]" on the title screen, and change "Sprache: Deutsch" to your prefered one.

Pacifistic Cyberfists
If it's not for the first time you visit the "Kill Dragan-mission there is absolutly no need to act violent in this game. If the only weapon you equip are the cyberfists all scanners, drones, bouncers and guards will ignore you as long as you don't break doors, attack anyone or ... say something stupid.

Nonsense dialouges
Beside some story-related dialouges (not all) there is no need to try to have a real conversation. All you have to do is to choose the most correct answer to the phrase you get. There aren't that much so you will recognize/remember them soon. Again, the dialouge doesn't have to make sense. You can threat a guys family one minute and then charm your way in his pants in the next if that's the way the randomized answers are presented. All that counts is that you choose one option that adds as much to the green side of the bars as possible.

The name game
Sorry. No help available. I have not a single clue how you're supposed to find out which of the given names is the right one. I tried to make a list but after a while the same names had different outcomes. I'm afraid it is completly random and all you can do is to rewind time until you pick a good one.

Best equippment
This depends on how you want toplay the game. Starting peacfully upgrading "Undo" and "Rewind" are imho more important than new weapons.
Also "Pheromones", "Precharger" and "Neural matrix" are essential.
A good buy's also "Flux Capacitor" and "Dash".
After "Dash" you can start to be aggressive and go for the "Body Armor" and the weapons.
As usual I prefered the shotgun as it has a very very long and wide range.
Have two or more in the slots so you can swap via TAB instead of reloading them and the walls and enemies will fall >:-)

Dashing through the ... club
If you would get shot in a fight while moving try the same path dashing (right mouse button) even if it's only for one square. Most of the time you can doge the bullets.
It is also the fastest way to get back to your car. ;-)

Rewind time
This game is all about rewinding time so use it. There are three different ways:
UNDO: Rewinds everything.
REWIND: Everything except Kai moves back.
TRACE BACK: Only Kais actions are undone.
I mostly used Rewind but it depends on the situation. Even Trace back proved to be usefull xD
But be warned: Some enmies aren't affected by time maipulation!

Destructive Achievements:
Destroying Bottles, Ballons, Barrels and Walls will happen naturally. Even more so if you use the shotgun inside of the club. >:-)
Same goes for the Kill-Achievements.

Keep your distance:
Sooner or later you will have to fight a large mob. It proved to be very effective if you dash away from them so most of them are in one corner of the screen while Kai is in the opposite one blasting the shotgun. What baffled me most was that most of the time none of the spectres tried to phase behind Kai. They all stayed in front of my shotgun... *g*

Drone Warfare:
"Have 100 enemies killed by friendly drones." Yeah... that one sucked. I picked a mission where I could gather a large swarm and then went hunting until all drones were down. The I aborted the mission, restarted it and did it again ... and again... and again. After a boring while the achievement popped although the counter lagged a bit. (It jumped from 91 to 100 in one kill?)
