Welcome to the Deceit 100% achievement guide.

I decided to make this guide because none existed on Steam yet, and I wanted more information and tips on certain achievements. Many of these achievements can be gotten in under 10 hours of playtime, however a few of them will require a lot more hours. So, if you're looking for a quick game to 100%, this isnt the game for you.

These achievments can be unlocked whether you're playing as Innocent or Infected.

Swag
Customize a character.
All you have to do is equip a cosmetic item obtained from the Loot Booth. The currency can be gotten through levelling up, or purchased. This one unlocked a while after I had equipped my first cosmetic, so be patient.

LVP
Get the least XP in a game.
This one you probably won't have to try to get, any game where you die first will likely unlock it.

MVP
Get the most XP in a game.
Just like LVP, this one will come naturally. If you're Innocent, try to activate as many levers as possible, capture objectives, and escape. Reviving people with the antidote gives a nice chunk of XP, so try to get your hands on one. As Infected, the same tips apply to levers and objectives, but you need to win. As long as you kill more people than your Infected partner, you'll likely unlock it.

Work Hard, Play Hard
Complete a total of 50 objectives.
This one will come naturally from playing enough games. As soon as you spawn, run around and complete every objective you can.

Mine
Capture 50 objectives that you didn't activate.
This one will take a little longer than Work Hard, Play Hard, because only capturing objectives activated by other players counts. They have to pull the lever, so follow someone around, and try to steal it from them. Careful though, as you get higher in levels, doing this can be considered suspicious.

Night Breed
Spend a total of 1 hour in the dark.
This refers to the 90 seconds of Blackout, when you have to collect the fuses, that happens on each 3 stages of a game. Again, this one will come with enough games played.

Sit Down
Down a total of 1,000 players.
You can do this as either an Innocent or Infected, but the sheer number of players you have to down will take you a while. Just make sure if any player is being shot down, you hit them a few times too, to count towards this achievement.
Edit: I achieved this one at about 120 hours of playtime.

Stay Down
Kill a total of 100 players.
Executing as a Terror, voting players out, and killing with a lethal injection all count towards this achievement.

We The Best
Reach max level on any character.
The official description for this one is a little confusing, but all you have to do is reach level 100. Doing well in games gets you more XP, and you can also purchase XP boosts to speed this up. I currently don't have this one so I can't give a good estimate on how many hours it takes, but I will update this once I've unlocked it.
Edit: I achieved this one at about 180 hours of playtime, with the help of XP boosts, bonus XP from playing during events and XP rewards from the recently added challenges.

These achievements can only be unlocked when playing as an Innocent.

Camaraderie
Escape the Asylum with all other innocents in the game.
All 4 Innocents need to escape along with you for this. Being on top of inspecting suspicious people, and staying grouped to survive Blackouts and vote out Infecteds early is crucial.

Escape Artist
Escape the Asylum a total of 25 times.
Much like Camaraderie, this one just requires you to play enough games. Make sure you always have a camera or torch for the blackout periods, rush fuses, and communicate if you see obvious Infecteds.

Exterminator
Kill 10 infected players as an innocent.
Downing Infected players in Terror form does not count for this. The only way to get this is to kill Infected players when they are in human form with the lethal injection. The 3rd phase of the map always has 1 lethal injection in double objectives. Most players completely avoid this, even if there is a confirmed Innocent among them, which is part of what makes this one so hard to obtain. There also needs to be a confirmed Infected alive during 3rd phase, and you need to get the injections before Blackout. If you have revived someone, they likely trust you, so you can ask them to help you get the lethal.
Edit: I achieved this one at about 70 hours of play time.

These achievements can only be unlocked when playing as an Infected.

Double Trouble
Execute two Innocent Members as an Infected during one dark period.
One thing to note is that executing as a Terror has a cooldown. After it's been used you can only scratch, which doesn't instantly down people, and they can be picked up with E. The easiest way to get this is to stall the Innocents getting fuses by holding them, and distracting them with accusations or anything else to stall. Once the Blackout timer runs out, you can enrage and turn into your Terror form regardless of how much blood you have, so I think this would be the easiest time to get Double Trouble, seeing as you won't run out of blood.

Executioner
Personally kill all the Innocent as an Infected during a game.
This one is tough because not only can your Infected partner not kill anyone, you can't vote anyone out, or win by the Innocents running out of time. When I first started playing, no one spoke in my games so Infected games were easy, looking back this would be the best time to get this one. Communicate with your Infected partner and have them split one person from the group at night for you to pick off during Blackouts, and stay seperate to stay full blood for the Blackout in every phase of the map.

This is my first guide, so I hope it was helpful for you!
If you have any questions you can leave a comment, I'm pretty good at checking Steam regularly.
If this guide was helpful, I'd really appreciate a rate and/or favorite.
Feedback is also appreciated :)


Edit: As of 2021 the new devs are taking this game in a somewhat different direction. I no longer play this game as I got my 100% a year ago, so I cannot help answer questions about any new or changed mechanics they implement.
