Here is a guide on how to get all achievements in POSTAL 4: No Regerts. Spoiler Alert!!!
Story/Unmissable
-Look ma, I’m a HOBO!“Make your homeless sign”
Unmissable
-Holocaust: Part Trois
“Reunite with an old enemy, again”
Unmissable
There’s not much to say about these, you’ll get them just by progressing in the game.
Challenge Playthroughs
-Passion of the Christ 2: Crucify This“Completed the story with no kills”
Finish the game without killing anyone.
-Non lethal weapons (the taser, non lethal way to use the rattler, etc) are extremly useful
-DON’T start the game on any day after monday, you can place the milk you get on Tuesday to skip the final boss, place it on the table before starting the cutscene.. It might still work if you start on Tuesday but better safe than sorry
More details coming soon.
-Roadhouse
“Beat the game by only using kicks to open doors and kill people”
Pretty self-explanatory, you might be able to load a save from before the end of a pacifist playthrough and kick some people to get it.
Errand Related
These are only obtainable during certain errands, keep an eye out for them.
-Can we fix it? No we can’t!
“Hit all barrels with an immigrant during the Border Smuggler errand”
On Tuesday, throw an immigrant at every single barrel. Two are accessible from the very start, and a big pack of barrels gets pulled into view near the end
-Mean Kitty
“As the Cat Dude, kill 10 chicks”
On Tuesday, after one of the errands turns you into a cat find and kill 10 little chicks. I got this achievement after killing only 5.
-Highscore, what does that mean?
“Beat all highscores of the Scooter Challenge”
Not strictly errand related, but I don’t think this appears after Tuesday. On Tuesday you’ll get a race side quest. Finish the race faster than the #1 leaderboard position
-Breezy, not sleezy
“Get all 10 petition signatures using the drag outfit.”
On Wednesday, ask a couple people to sign your petition. This will unlock a side quest, go to the objective marker, select the sexy outfit in the mirror and then ask people to sign your petition until you have all 10 signatures. (You’ll also get the classic outfit added to your inventory)
-4 can play that game!
“Kill 4 fast-food workers during the Mexicleaner errand with the FOURnicator”
On Wednesday, get a FOURnicator and some ammo (you can buy these from the vending machines), then during the Mexicleaner errand kill 4 fast-food workers. I got the achievement by using a single barrel for all of the fast food workers.
-Lame of Thrones
“Install all bidets for Mike without killing anyone”
Pretty self-explanatory, I recommend doing this while going for a pacifist run
-Lynched
“Kill all of the mountain men on Thursday”
On Thrusday you’ll start in a spooky forest with a bunch of mountain men. Before going back to the main part of town kill all the mountain men. I recommend shooting loudly after getting your weapons back as this gets the mountain men to come to you. The achievement pops after leaving the forest and entering the Vince cutscene
-Scooter Tutor
“Beat the Fix Race errand by crossing the finished line with a fully bloodied scooter”
On Thursday, kill everyone in the race (the leaderboard on the left will update) and then win the race, maybe you can do it by letting the red scooter win, killing everyone else and finishing right after the red scooter but I didn’t try that
Murder
-One Side, Gramps
“Run over 50 people using the mobility scooter.”
You’ll likely get this by playing the game normally
-We still ain’t got no budget!
“Kill 100 pigeons from thrown cages”
The way I did this was to find an area without anyone nearby, then I threw a bunch of pigeon mines and then shot a rocket into the pigeons.
-Yippee Ki-Yay
“Kill 7 people at the same time using Dude Eye”
“Dude eye” is the revolver bar. Kill a couple people with the revolver until the red bar is full, reload, and then use the alt fire to kill 7 people in one go.
-Dude Vinci Code“Collect all the paintings in the game”
-One of Uwe’s Best
“Finish all rampages”
-Still playing with dolls!
“Collect all Krotchy, Kunny, & Larry collectibles”
Check out the (as of now work in progress) sister guide which I contributed to!
Other
-And remember, respect is everything!“Reach maximum heat level with the police and survive!”
Get a wanted level (you don’t need me to explain how to get one), and after getting it to the max a police assault. Simply survive it, wait for the wanted meter to run out and the achievement will pop
-PISSASSO
“Turn 10 toilets yellow with piss”
You might notice that no toilets are turning yellow, that’s because the effect either isn’t in the game or it’s just broken. Just piss in every toilet you see and eventually you’ll get this achievement
-I Wanna Dance With Somebody
“Find the secret crack den!”
Get to the trailer park area near the prison, and crouch under the one with a big fence.
-Don’t forget to wash your hands!
“Flush after taking a piss in a toilet”
For whatever reason not every toilet will work, The more round ones do work though. I did this in the KTDF building
-No Way Trailer Home
“Finish a mission with all 3 Dudes”
When you start a new game you get to choose a voice actor (Jon St. John, Rick Hunter, Corey Cruise, and in a future update Zack Ward). Simply finish at least one errand with each one of the voice actors (visiting the job agency on Monday counts as finishing an errand)
Thanks to Botul for his great guide, all credit to his effort. you can also read the original guide from Steam Community. enjoy the game.
For No Way Trailer Home achievement all you really need to do is start a new run for each Dude and reach thee job agency,if you know where it is,you can go there straight after you create a Need a job sign,no need to ask people for work
