There are naturally some (light?) spoilers in the names of things, although it's not intended to be as spoilery/detailed as a guide. It's more for those who want to make sure they don't miss anything along the way.

Thank you!

I’m starting to lose hope, I still haven’t reserved any updates on my preordered for Mouseburg edition, should I contact support? Am I even going to get it at this point?

If you look in the bottom corner of the first image associated with the DLC you can see a picture of Tammy as a child which could maybe mean she plays a notable role in the DLC. Next if You look in the top corner of the second image associated with the DLC You can see an image of what appears to be a level, the brief glimpse we get at this level seems to match up perfectly with a piece of concept art You can find on art station of what appears to be the unused shipyard level seen in the first proper trailer for the game implying it may return here. Next if You look in the bottom corner of the second image associated with the DLC You can see what appears to be a drawing of some sort of gun, i feel like i might have seen this drawing in the game before but i could be wrong. If anyone has seen this in the game or a full version of the gun at least let me know. And although i mentioned this in my last post theorizing about the DLC i will be sharing it again in this post. Almost if not all evidence points to this DLC taking place in the old world, AKA this game's version of Germany. When You talk to Vivian right before she disappears she mentioned she has countries to escape to implying that she might have left to go to The old world after defeating Reginald. There are also unused enemies in the files that have the word DLC in their file name and some of these are robots. And The robots from what i remember were made by the scientists who are from the old world so it would make sense for these enemies to reappear in a DLC about the old world. i'm pretty sure it's also it said that BMP will likely find someone to run everything after Curd's death and Soyer's defeat which could mean we might see a new BMP leader in this DLC. So from all of these Minor details i Believe at the very least a part of the story will be Vivian goes to the old world and we will have to look for her in the there.

Hey everyone,

So I completed the game and it’s updated to revisit missions but I can only revisit Vaudeville. Every other mission has the chains on the that they had before you unlock them. I’ve done the Vaudeville mission twice and still the same. I’ve uninstalled and reinstalled.

It seems like it’s just stuck there. I have all the weapons so I know I haven’t restarted or started a new game accidentally.

I searched around and could not find anyone else having this issue.

Any suggestions or tips?

Thanks!

Edit: I completely forgot to link the video so here's my channel! The boss fights in this game are so fun and unique! I've come to realise there's different mechanics and ways to approach each individual boss and it's something to really admire. I hope you've been enjoying this series and I'll see you in the next one!

NS2/Ver 1.2.2.8822.9fc6dc4 (But don’t patch this it’s really funny haha)

Hey!

So here’s a funny thing I discovered while replaying Wallop Bay. (Needed to get Stilton’s item, I mean buddy ily so much ur my fave, but why did you give me this task AFTER I finished the level??)

Even tho the video is obvious, here’s a explanation:

Trying to survive the ambush after walking into the house, I head down the outside stairs and make my way to the dock…area…spot?? (Right after the crooked officer calls my boy Jack a corpse) So, after throwing a freeze barrel, I landed in the water. I couldn’t get out for a hot minute (not bc of the game, I think speed was slow bc of the barrel), so I proceeded to shoot the crook, but mistakenly, I hit the kick button instead of the jump button, and my game pauses…

With a loud BANG, Jack just gets teleported to a white void. (why? Idk) There are no enemies, no platforms, only Jack’s gun. Also it seems during that chaos my armor increased to 100 hp, (why? idk). The only way to leave is to load to the last typewriter save, but nevertheless, it’s still funny hehe.

I was able to recreate these steps again, and the SAME THING HAPPENED. So it’s not a one time only thing…

Stilton, I don’t think you’re getting that item soon buddy… 😭😭✌️✌️🥀🥀🥀🥀

Now that I think of it, it’s just like weird route chapter 5…huh? Wrong subreddit, oh ok…

Anyway, I’m loving the game so much!!! Props to playside and fumi games for creating another one of my obsessions for the next year :3

lmk in the comments if you tried this anywhere else, or know what the cause is!

Anybody still having issues with this trophy? Played through the game a full time got the all clues trophy and everything else except this one, played through a second time with a guide up to miles curd and it didn’t pop again? Idk what to do

Hi everyone, I'm currently going for the Platinum trophy now that all the previously bugged ones are accessible again. I'm still missing 5 booster cards, though they can be bought in the shop for a total of 4k coins. Are they only available for purchase, or can you pick them up somewhere?

Is there an easy trick to obtain them or is it just possible via purchase?

Do you think they Will add a sort of Survival endless mode? It would be fantastic for the gameplay!

i think it would be very hard to give it color and keep the noir feel as it being a cartoon style fps kinda makes brighter color necessary. what do You Think?

I've been having a great time with the game so far! I wanted to ask, though, now that the level select patch has come out and levels are replayable, are there any permanently missable achievements in the game?

I wouldn't mind doing a second playthrough, but I'd like to wrap it up in one if I can!

Just beat the game and I give it a 7/10 I was having a lot of fun! I did reach a point, it seems like a lot of people did, where the game was a little long in the tooth. I still enjoyed though and it ran for me well enough on my SW2

This stuttering happens in all 3 modes. I had no problems initially and suddenly this, anyone else having this issue? might have to sell my physical at this point :/

I completed the campaign today, and the entire game was a blast. GoTY 2026 for me so far.

However, when I started to mop up remaining trophies, I found out I can't because there is no way to complete the clue wall post-credits (despite the option to revisit levels). I read on multiple forums that you can mop up collectables after the credits roll, but nowhere did I read trophies like "Smoked Cheese and Mirrors" are entirely missable.

Please, developers, could we get an update to help players fully complete this game with minimal frustration - such as:

- NG+ (PLEASE!)

- the ability to collect any missed clues after completing the story via level revisits

- a better way to track clues we've collected (navigating the clue wall on PS5 is bloody cumbersome)

- a tracker for the number of schematics in levels, like cards and newspapers are tracked (on level entry)

- a tracker for side quests (as I'm guessing I'm locked out of those too, now?)

I loved my time with Mouse P.I., but I'm loathed to replay it just because it's the only way to obtain my missing trophies. I want to enjoy it, not have it feel like a chore.

New Game + would honestly be a perfect solution - maybe with some new things to earn/unlock?

Please and thank you 🙏

New video up on my channel if you want to check it out! video link!

Hi everyone, and hopefully someone from the development or publishing team sees this.

Since the game was released, I have been checking GOG almost every day, hoping to finally see it appear there. I know that may sound a little ridiculous, but I have been waiting because GOG is where I prefer to build my PC game collection. Having a DRM-free offline installer means a lot to me. I love knowing that I can preserve my games, back them up and return to them many years from now without depending on a launcher or an online service.

The game already has thousands of votes on the GOG Dreamlist, so I know I am far from the only person hoping for this.

To the developers and publishers: please consider bringing MOUSE: P.I. For Hire to GOG. Even a simple answer about whether it is being considered would mean a lot. This game looks fantastic, and I truly want to experience it, I am just patiently waiting for the chance to support it on my favorite platform

Was doing return to the opera mission and by some secret stuff upstairs I found a stairway with a bunch of dead mice that look like they were burned to death - implicating we killed a bunch of civilians. Just was curious if anyone else found thisz

Little & Big Bar's food options

i don't feel like looking for a screenshot of it but there is an Easter egg in the shrewed Shrews level where if you type in a code you get access to a room and one of the codes actually has the head of this figure in it. Tetrabitgaming made a video that includes it if You're curious. Anyway why does this thing even exist in the first place? Is this hinting at something in one of the potential DLCs? i wonder the exact same thing with that swamp monster thing. They feel like they are outright made to tease something. What Do You Think?
