Been running this heist solo quite a bit lately and honestly its not too bad once you get the approach down. The kosatka submarine is definitely your best bet for getting in clean, and the drainage tunnel entrance keeps things simple. Pink diamond is what youll usually want as your primary target these days, and for secondary loot your best solo options are gonna be cocaine and cash since the gold rooms need two people.

Starting out with the sub approach, you can swim right to the drainage tunnel and get inside pretty smoothly. The guards have some predictable patterns, and if youre careful with your timing, getting to the office is straightforward. Good to know that the fingerprint hack gets way easier with practice, i usually knock it out in under 30 seconds now.

For filling your bag solo, focus on cocaine first since its worth more than cash, and try to grab spots closer to your escape route. The whole thing should take under 15 minutes if youre going for elite challenge, which is totally doable once you learn the routes. You can expect around 1.3 mil average for a decent run, not bad for about 45 minutes of total prep and finale time. Just remember to stay in stealth mode, cause once the alarms go off things get way messier than they need to be.
