Steam Link: https://gamebanana.com/maps/186867 not steam I know, but game banana is a good place to find maps and it was posted by the original creator of the map. EDIT: Forgot to add that it's not just a csgo map, it works 100% in gmod.
Suggestion: Update this to the new version of lego jail as the old one can get a boring.
Description of Suggestion: There a new features like Four Corners, a stage for prisoners with a large playable piano that makes sounds, a vip cell for prisoners that they randomly spawn in, more hallways so therefore a bigger map to explore and many other nooks and crannies that were added in this newer version.
Here are some screenshots that I took:
The Four Corners game-
The VIP cell with and added bridge-
The lobby area leading to Four Corners-
The stage/piano area-
How it will improve Jailbreak: New maps meaning people will have more fun exploring when they first play the map and prisoners in general will have more fun playing. Also lego jail gets more stuff for the warden to play with and prisoners can run off further to find guns as there are also more spots for guns.
