In the guide I will often mention maps from the challenge mode, which you can find in the main menu of the game. In this mode, you have to complete maps against the clock and compete with other players, but its main use is to be able to replay any map from the main game except Chicken Sky. There are also two additional maps available in challenge mode that are not in the main game: Apocalypse of DON and WTF_HELL. Unfortunately, you can't use items in this mode, so getting some achievements becomes more difficult.

First you need to open the main menu of the game and go to the tutorial. Once the map loads, you can go straight to the right and fall into the abyss. After you die, you will get the achievement.
There's also a more symbolic way - stand on a pie and die with a rolling pin.

It would seem that all you have to do is shoot chickens quickly. However, due to the great ALTF4 bugs, you may not get this achievement even after several hours of play. So if you can't get it, start the first map and start shooting chickens continuously. I got the achievement this way in four minutes.

As you progress through the game, you will encounter balloons with save signs attached to them. You need to shoot a chicken into the balloon, after which it will burst and the save sign will fall to the ground.
When you stand on the sign, the game will save and you will get the achievement. Please note that all saves are one-time use.

As you progress through the game, you will find cages with chickens. If you shoot them, you will get a random item. All items are activated on the same button as the roll. Each item has a unique ability and you need to find the one that turns the player into a chicken. To get the achievement, you need to complete any level in the chicken form. You don't have to be in the chicken form the whole time, you can just reach the portal the normal way and only then use the item. It is easiest to complete on The Eggners map.

To get the achievement, you need to die from water 50 times. Just find a convenient cliff and jump down.

On the Chicken Sky map, when you are flying the airplane, you just need to keep standing. After the airplane explodes, you will get the achievement.

To get the achievement you need to die from a cannonball. You can find these cannonballs on the Don's Inferno and Apocalypse of DON maps.

On the Don's Inferno map you need to reach the top of the building, there you can find dragon eggs on one of the platforms. To get the achievement you need to jump on them and crush them, this will make the dragon angry and he will kill you.

On the Sacred Madness map, you must enter the wrong door with the number 8 on it. Otherwise, the achievement will not count.

You must die from a pig to get the achievement. You can find pigs on the Sacred Madness and Apocalypse of DON maps.

On The Picture of DON map, there is a secret flying machine that allows you to skip part of the map. To get the achievement, you must jump on it at the moment when it takes off. Otherwise, you'll just get trapped and won't get the achievement. However, if you go the normal way, in most cases you will not have time to jump on this machine, because it behaves very randomly. Therefore, you need to take a special route so that you don't activate the flying machine right away. First you need to get to the two huts and with the help of a fence climb on their roofs.
After that, carefully jump onto the stone wall of the tower and get ready. As soon as you jump down and touch the floor, the machine will start to take off. You need to get in time to the part of the wall that the arrow is pointing at, otherwise you won't be able to jump to the machine.
If you successfully stand on the paddle, the achievement should be completed. You can also use this machine to cross the sea and use inertia to reach the mill. To do this, you need to jump at the last moment before the machine stops on the spot.

To get the achievement, you must die from a fish. You can find fish on The Picture of DON and Apocalypse of DON maps. However, on The Picture of DON, dying from a fish is very inconvenient, as they will throw you into the water when you touch them. To get the achievement, you need to die from a fish, not touch it.

On the The Picture of DON map you can find electric rails during the walkthrough. To get the achievement, jump on them and die from electricity. To find the electric rails, follow the path shown in the screenshots.
When you reach the intersection, you can choose any route you want. The rails are the same everywhere and you get the achievement anyway.

To get this achievement, you need to reach the final portal and complete the game. The final portal is located at the top of the tower on The Picture of DON map.

To get the achievement, complete any map in challenge mode. The easiest map to complete is The Eggners.

In general, this achievement should be given for completing the game without dying. But you can get it much easier. To do this, you need to complete any map in challenge mode without dying. It's the easiest to complete on The Eggners map.

On the Apocalypse of DON map you need to reach the moment with the dancing man. There is a passage next to him, which you need to enter. Once you get there, you will be killed by a huge hammer and you will get the achievement.

It's simple - die 100 times. The achievement is non-cumulative, which means that you have to die 100 times in one game. I advise you to do it together with the GOLD!? achievement, because one of its conditions is 100 deaths.

There are secret golden chickens in the game, they are hidden on every map. To get the achievement, you need to take one of these chickens in the golden knight skin. First you have to die exactly 100 times, because the golden knight skin is given for only one life. You must not lose it, otherwise you will have to start all over again. After that, follow one of the paths shown on the screenshots and take the golden chicken.
You need to get inside this house, to do this use some items and fly to the other side. You can also return here from the end of the level, but then you will be chased by an evil dummy.
Also, after picking up any golden chicken, your attacks will get a burning effect.
On this map the chicken should be on a stand, but due to a bug it doesn't move forward with the platform and remains hanging in the air.
In this place you need to enter the tavern and kill the dancing knight, this will open a secret passage.
First you need to climb to the top of the wall with traps. Then go to the right and carefully climb down the cliff to the chicken.

To get the achievement, you must die 1000 times. The achievement is non-cumulative, which means that you have to die 1000 times in one game. Also, due to bugs, you cannot complete this achievement on a single map. To avoid all the problems associated with this achievement, proceed as follows. Start a new game and die on the first map 200 times from natural conditions, to do this just jump into the water behind the portal. Then reach the second map with the airplane and also die 200 times by falling down. Die in the same way on the next maps. On the fifth map you will have accumulated 1000 deaths and you will get the achievement. Also you don't have to die on each map exactly 200 times, the most important thing is to divide the deaths between all maps and not to die on any one map too much. For 1000 deaths you will get the ice knight skin.

To complete the achievement you need to roll 10000 times. This is a non-cumulative achievement, meaning you cannot quit the game until you have made 10000 rolls. Otherwise you will have to start all over again. The easiest map to complete is The Eggners. You need to enter the house and lean against the wall. After that, press the forward button and do a roll. This way the character will stay in one place. It will take you about 4 hours to complete the achievement.

To get the achievement, you need to complete the WTF_HELL map, but it will be very hard. It is best to use speedrun strategies, with its help walktrough becomes much easier. The main point of the strat is to use trap platforms, which can throw your character very high. To get to the first platform, you need to carefully run along the edge of the island and to do a roll before the spiky column, because you can't jump normally near it thanks to the crooked hitboxes.
After you get to the platform, you will need to catch such timing that there is no swinging saw nearby and the platform is completely on the ground. At this point you need to run to the edge of the platform. A moment after you step on it, you need to do a roll, as a result of which the character will maintain vertical acceleration and fly forward. If you do everything correctly, you will be able to fly to the next island.
But be careful, this island is inhabited by very evil rabbits, which are almost 100% likely to kill you if you land near them. So you need to lure them out and hide behind a rock, then the rabbits will run diagonally and fall into the water. After you deal with the rabbits, you need to get to the spinning logs near the ice platform.
With the help of the last log you need to jump on top of the trap platforms. This is quite difficult to do due to the fact that the platforms are slippery, as well as the ice underneath them. It is best to jump sideways when the log is almost vertical and adjust the character's position by pressing left-right.
As soon as you jump on the platforms, the cannonballs below will start moving. If a cannonball touches a platform, it will fly off hard and push other cannonballs away. This will start a chain reaction, so you need to act fast. You need to get into roughly the same position as in the screenshot, and then shoot the chicken into the platform. To maintain horizontal acceleration and fly at the right angle straight into the portal, you need to jump the moment the platform has opened almost completely. If you jump too early or too late, you'll fly past the portal or stay in place. The most important thing is to hit the portal with your character, then you will win even if you die.
