This game is very well scripted indeed and also very well accurate to the game, the actual scenery is from the game too. Let me just say one thing, this game is a big hit but when he's done building all of Chicago, this game will be one of the most popular on roblox.
The phone you are equipped with is very powerful and has limits to what it can do, for instants, you have to unlock a skill in the skill tree to upgrade your hacking. The original game has combat, driving and crafting, but i'm sure the creator of this game will add it soon enough.
This is one of the roblox games by far which is still in development. I am sure excited to see the future of this game.
