Guide for Casino Heist
I would suggest you watch this yt video and you choose if you want it really ez, or a little bit hard.
Find all the ways in and out. This Carries over from all the ways you can make the heist, so don't worry about doing the same thing over and over.
Get an arcade close to the city, or in it. Never Get the cheapest one. Its really bad, i use it and its annoying. Of course if you have the money, if you don't. Sadly the cheapest one will do.
One of these are good, just. Don't go out of the city if possible!
All prebs and setups can be done in a invite only lobby, so if you have trouble with others destryoing ur stuff, do it in an invite only. It helps
Tho if possible, and you find a chill lobby, you can do it in there.
Do the heist with friends, or with randoms with mics, it helps. Nothing is more annoying than having no way to talk with others.
If ur cover is blown. Stay together and focus targets, so none of the npcs can stay alive for a long tim
Get all the Signal Jammers, this can help you alot, because this will give you more time to get money in the vault once you enter it, and it also gives Money and RP.
Also get the van that sometimes can spawn on the map, it will be a small blue dot, so look around for that. It will give you a better gunman!.
I hope this guide has helped you!
