There are three immunities in the game; the aspirin, sandwich, and gasoline. Each these immunities will negate certain deaths in the playthrough where they are collected. In almost all instances the game will tell you it was a good thing you got X immunity because it prevented Y death from happening. That being said, immunities only really prevent perhaps 10-15 deaths out of the 115 possible in the game.

This is most likely the first achievement you'll get as soon as you start up the game.

This is pretty easy. Just keep playing, by whatever method you employ, and die 100 times.

Another pretty easy achievement. Just keep playing until you hit 1000 deaths!

A little trickier than the others but bound to happen at some point. Just make it home and you unlock this achievement.

Interesting point about the game. This is guaranteed to happen, at the least, on your 116th game if you do it in one run. Why? The game does not let you experience the same death twice during a run, thus you will get it automatically at the end of a 116 game run. If you don't get it sooner.

Outside of having to go back to the main menu (for now), most of the achievements are pretty straight-forward and easily achieved by button mashing. The biggest confusion seems to revolve around the Trifecta achievement. This is where you have all three immunities at the same time and, sadly, requires you to go to the main menu to unlock it. However, until this is fixed in the first patch, this achievement be obtained even without going to the menu to do it.

The only way to get the achievement is heading to the bathroom first, then the sandwich, and then go get gas. But the chance of death is even greater going this path as you have to get through more pages just to get it. Good luck!

This one is rough because you have to keep playing and playing. Most people get to about 105 or so and have a hard time getting those last few deaths because of how the randomization engine is built. Again, if you play a 116 game run, you should get them all.

Also fairly easy to get. You have to get the Steam-only deaths.These are scattered amongst the pages. May GabeN lead you!

You have to experience all Sabotage Update related deaths. They are only possible if the Saboteur has activated the trap on the specific page. They are definitely more tricky than the others.

Since the players can actively screw the saboteur and vice-versa we figured an achievement might be in order. Any saboteur who cannot win the elephant raffle during their window of opportunity is awarded the Sweet Revenge achievement. Shouldn't it be the other way around? Who says it won't be?

As the description says, you have to be the Saboteur five times. Simple? Well, only one person can be the Saboteur at a time so good luck getting that spot.

As Saboteur, your traps have to kill over 666 players. Considering your traps affect EVERYONE playing, it should only take a few times as Saboteur to get it. Every time you set a trap you will also get a +1 to the progress in this.

To be noted, if a player ends your run as saboteur you will not get any of the kills accumulated and they get a +1 to their saboteurs thwarted progress instead! However, there is a decent cushion between when you can close out your run and before they can... by about 50 kills or trap disablings.

This one is easy-ish if you can get to be the Saboteur. All you have to do is make it to the Fun Park and win the raffle. The raffle, as raffles are, is random. This might take a few tries. However, since other players are trying to stop you be deactivating traps and outright dying you may not make it your first time as saboteur!

When you aren't the trapper you may see an option to disable a trap on the page. This is only if the Saboteur has set that option on the page. Do this about 666 times and you're good to go.

This might be one the most difficult to get. Any time the Saboteur's run is ended by a player, that player gets progress on this achievement. Now, there is only one player who can do this per Saboteur... provided the Saboteur doesn't end their run or as long as the timer doesn't go off. Good luck!

Much to the dismay of achievement hunters we decided to add this last (we swear) achievement to One Way To Die for the Halloween Update (our last, seriously).

Like the other "get all deaths" achievements, you only have to experience each of the 10 special Halloween deaths. These are only available / active during the Halloween / Day of the Dead season, from October 29th to November 2nd.

If it is not during that time period, you can set your computer's clock to any day in that range to enable Holiday Mode. Holiday Mode is on when you see the jack-o-latern screen and jack-o-lantern button in-game.

Yet again, much to the dismay of achievement hunters we decided to add this actually last achievement to One Way To Die for the X-Mas Update. Our last one, really this time.

Just like the other "get all deaths" achievements, you only have to experience each of the 10 special X-Mas deaths. These are only available / active during the X-Mas / New Years season, from December 22th to 31st.

If it is not during that time period, you can set your computer's clock to any day in that range to enable Holiday Mode. Holiday Mode is on when you see the wreath menu screen and Santa hat skull button in-game.

This achievement usually pops for anyone playing any version of the game from v4.0.0 and on. It was added to mark the big overhaul patch in 2016.

Some users report that the achievement may not fire until you 'sync' you game with Steam; however, it should just automatically fire once the game starts up if you don't have it.
