MUS: PI for rent has several easter eggs for everything from classic 1930s animation to modern TV shows, popular culture and video games, but its Resident Evil 2 The Easter egg is so thorough and so present that nothing could even compete with it. Obviously, Easter eggs are a time-honored legacy in video games, and MUS: PI for rent follows with years of Easter egg designs. Like I said, not even Resident Evil itself can fully compete with this.
Minor spoilers ahead for MOUSE: PI For Hire, Resident Evil 2 Remake and Resident Evil Requiem
For example, Resident Evil Requiem is chock full of Easter eggs for the franchise. Some of these require an extra keen eye, such as the toy farm and the train at the Children's Home which refer to the original Resident Evil and Resident Evil Zero. Others require a free camera tool, like how Grace examines the events Resident Evil 7's Dulvey Incident in the Wrenwood Hotel room with his mother. Additionally, the Rhodes Hill Chronic Care Center lounge area has a liquor bottle marked AVERNICO (which uses the same letters as Veronica, leading many to believe it is a Code: Veronica easter eggs), and Emily reads a Braille translation of the book, Village of Shadowsfrom Resident Evil Village. All this is to say, Resident Evil know how to make Easter eggs, and Mouse PI for rent gives it a run for its money.
I marathoned all 29 Resident Evil games for the 30th anniversary, and here are my official rankings
I replayed all 29 Resident Evil games for the franchise's 30th anniversary and ranked them from worst to best.
From RCPD to That Alligator
It's hard to see the white on white in this screenshot, but it says “Welcome Leon.”
Early in MUS: PI for rents story, players will enter the Mouseburg Police Department. Of course, a game with a police department is not an easter egg for Resident Evil 2s Raccoon City Police Department approach, but exploring it provides RE Requiem Vibes of the broken down RCPD, like there's a structural sense of sameness there, even though the police department is active. But what saves it is the end of the level where players see the “Welcome Leon” sign. No doubt, thus a reference to the RCPD and how Leon even runs into it again in RE Requiem.
That's where a lot of Easter eggs would end up, but that's not what happened here. MUS: PI For Hire's level structure then feels like exploring a 1930s version of Raccoon City. From the Mouseburg Police Department, players must travel through a subway – a more obvious nod to it Resident Evil 3. The thing is, Raccoon City is pretty similar in layout across all games. Players know that the subway is connected to the sewers, which is explored in both Resident Evil 2 and Resident Evil 3 (and their remakes).
However, only in Resident Evil 2 is the giant alligator chase sequence that Leon and Ada go into. After exploring the subway and then the sewers, MOUSE players then find themselves…with a giant alligator boss fight…except this time the alligator has a gun. Giving that alligator, which is clearly a reference, a gun is the funnest thing anyone can do in this situation.

Overall, from the moment the Mouseburg PD starts feeling like the RCPD to defeating the gator with a gun, MUS: PI for rent feels like a new one Resident Evil 2 remake. And it shows how skillfully the game uses easter eggs.
