Dead by Daylight

I did this half and half solo queue/SWF.
The perk build that got me this was as follows:
1. Sole Survivor (Laurie Strode's unique perk) for the 50% door opening speed. Also comes in handy against most if not all aura reading perks/addons etc that killers bring.
Bear in mind this perk relies on you being the last alive.
2. Wake Up (Quentin Smith's unique perk) for 25% door opening speed. Paired with Sole Survivor you'll have a door open well before the killer can come check it.
3. Low Profile (Ada Wong's unique perk) Free Iron Will and Lucky Break for 90 seconds upon being the last Survivor (especially if the killer is being greedy and trying to get all 4 Survivors sacrificed) is amazing, as you can then (relatively) safely run for a gate and hide to wait out whoever the killer has left on the ground to find you.
4. Anything. I often used Unbreakable (William "Bill" Overbeck's unique perk) to revive myself in situations where everyone manages to go down and the killer hooks everyone else. Off the Record (Zarina Kassir's unique perk) was a good choice when killers felt particularly tunnely and the free 80 seconds of Iron Will and Distortion didn't hurt.

Now, if you're in a team, this build probably won't be useful. You'll likely want to bring perks like Prove Thyself and We'll Make It for efficiency.
This build is more catered to solo queue.
As much as nobody wants to admit it, solo queue is the Wild West. It's every man for himself, and so if it comes down to it it's them or your achievement. It might seem selfish, but if you're put in a situation where there's a chance you could get a gate open and escape, go for it. There's no way of knowing whether or not that random would've helped you if the situation was reversed, so if you get flak for it just ignore it.
Thats why I'd recommend doing this with crossplay on; sure you'll get matched against sweaty PC killers, but at least you won't get hatemail from your teammates when you choose to save yourself vs getting yourself killed for nothing.

Raccoon City Police Department has been split into two different maps; Raccoon City Police Station East Wing and Raccoon City Police Station West Wing. Both of these maps will count towards this achievement. You will have to be the one to open the exit gate yourself. It can not be opened by someone else otherwise progress will not count, so make sure to position yourself where you can get to the exit gate switch within reasonable time of fixing the last generator. Both of the exit gates for each of the map variations are on the ground floor with the main gate being at the center of the Police Department. General base perks that will help speed up unlocking the exit gates aswell as getting a speed boost ahead of your fellow teammates are "No One Left Behind" and "Resilience". If possible I also suggest running Claudette Morel's teachable perk "Self-Care" to heal yourself and Adam Francis' teachable perk "Deliverance" to unhook yourself that way you aren't having to rely on your teammates to heal or unhook you. The use of the Rare Offering "RPD Badge" can be used by you or another teammate to highly increase the chances of the next map being one of the Raccoon City Police Station Wings.

RPD is now split into Raccoon City Police Station East Wing and Raccoon City Police Station West Wing. both count.

You need a specific 2/35 maps for this achievement so planning on only hoping for RPD every game is a waste of time. Using an RPD Badge or joining and leaving games when the dc penalty is off are the best ideas.

You only need to have the last touch on the exit gate powering to leave, so if a teammate 99s a gate to taunt the killer or to ensure their teammates safety, you can power the last 1 or 2% and leave.

This builds idea is to hide around the map until all your teammates die

The build:

spine chill is a universal perk that lets you tell early if its a stealth killer and know how close the killer is to you if you havent mastered the terror radius mechanic. even if you are a multi-thousand hour survivor, spine chill is nice to know when the killer is headed your general direction and when to hide when you know its a stealth killer looking at you or in your direction

self care a clauddete perk or boon circle of healing from mikaela so you can heal yourself without needing to be close to your teammates and you get more than one or two heals than with only bringing a medkit

clairvoyance is another one of mikaelas perks and this one activates after you cleanse a dull or hex totem and cannot be used with an item in hand. This perk for 10 seconds shows you the aura of gens, hooks, and the hatch within a 64 meter radius when in tier 3. This is huge and very important for knowing which gate to hide near in a hatch game and helps you have an idea if you have the 10 seconds you need to open the gate since they will most likely visit the gate closer to them

sole survivor is a laurie strode perk to open the exit gate 10 seconds faster when your the last alive and it hides you aura for 24 meters from the killer for every dead survivor. you dont need wake up as the gate locations are the same every time depending on the wing you have and the extra boost isnt necessary.

If you are going against a high mobility or a teleportation killer like nurse, blight, sadako, demogorgon, or wraith, this method is scarier but with sadako retreiving her tape takes out the teleportation factor and facing a demogorgon is rare since they removed his dlc last year. blight and nurse are almost equally terrifying but with luck and calculation from clairvoyance they will check the wrong gate first and you will leave.

sometimes a killer will stand on hatch until they see you to ensure they get the 4 kills but the majorityof killers dont do this and if this happens hopefully you can wait them out. Dont get idle crows at any time during the match since these progressively get louder and more obvious to the killer. Running and walking in the same spot or general corner wont work
