Okay so the idea is a Roblox game called “Vigilance”
It’s a game with similar gameplay to RDR2, Batman Arkham Shadow, and others.
The game itself takes place in a city that never sleeps. It’s got a noir filter over everything, and robloxians populate the area. Certain robloxians are either citizens, delinquents, politicians, law enforcement, cultists, mafia families, etc. It also uses classic textures (aside from shirts, pants, decals, t-shirts, hats, and custom faces). I also want it to be voice acted.
So you play as a guy known only as “Detective”. He’s a nameless, mysterious detective persona with an assistant, “Wesley Jones” (A.K.A “Wes” or “Mr. Jones”).
In the game itself your goal is to stay on the good side of Law Enforcement, solve crimes, stop delinquents, etc.
You always have an option to kill anyone, but doing this lowers your reputation (the RDR2 aspect). You can also do mundane deeds, tasks, or solve crimes peacefully which can better your reputation. There will even be endings corresponding to your playstyle.
The game also focuses on a storyline (The Batman Arkham Shadow aspect). All missions, locations, and alibis all contribute to something bigger. It all contributes to an eventual culprit. That of which is kept secret.
