Cayo Perico Heist Help

[PleaseHelpMePlay]

I’m new to GTA Online and can’t do this heist because there are things missing in my game or there are bugs/glitches.
 

Sources say the best entry point is the drainage tunnel. My game only gives me the Main Gate option. Doesn’t even have the plasma cutter mission.

 

Silencers don’t work because when I kill a guard a chopper is on me instantly.

 

The list goes on and on. I’m just asking for help and am willing to PAY! Whether it’s a simple fix or something that requires a hacker I will PAY!  I’m just sick of having to buy shark cards. 

 

NOTES:

I’m in Invite Only Session. 

All prep missions are complete.

I deleted and reinstalled the game - didn’t work. 
I’m playing on PS5 with the latest updates.

Yeah the Enhanced version has lots of bugs sadly. You can't do anything except try and play on PC or PS 4

You didn't forget to initially scope out the drainage tunnel did you?

[Aquamaniac]

Can't help with the bugs. You have to scope out the drainage entry first, did you?

 

Killings guards might trigger the alarm if another guard watches it or a camera will see it. Watch some youtube videos how to do it stealth or read the other threads here, properly done you can melee all necessary guards with the drainage approach, no silencers needed.

Scope the drainage tunnel so you get the cutting tool options (only needs doing once)

 

 

And only kill people you need to.
