Shot By Both Sides.  

Shot By Both Sides. #CP2077 #Phantom Liberty #PS5
There's a bit of mystery to this quest since you aren't given the full details of what is really happening until the end. But from a gameplay standpoint, you don't need to know everything about Bree and her corpo enemies until you're forced to make a big choice at the end of the job. Before then, you must know how to find an access card, locate Bree, and get past several traps. All that information and the consequences of the quest-ending decision are in this guide.

HERE THE THREE CHOICES YOU WILL GET AT THE END:
Killing Dante
Letting Bree have the data by killing Dante will surely please Mr. Hands and give you the payment. However, you will find out the next day through Mr. Hands that she sold you out to the Netwatch, which is now on the hunt for everyone involved.
Dante will also drop Ol' Reliable after you defeat him.
Killing Bree
On the other hand, you won't get anything from Mr. Hands by taking Dante's side as you just killed the person who would've paid for the mission. You won't leave with empty pockets, though, as Dante will give you a cut for your help.
Letting Dante shoot Bree or shooting her yourself lets you have her Iconic weapon, Riskit.
Killing Both of Them
The option that will give you the best rewards is to take no sides at tall (or should we say, shoot both sides) and kill both Dante and Bree. You will get both Iconic weapons and additional eddies this way.
1. Let Dante shoot Bree or shoot Bree yourself
2. Take Riskit from Bree
3. Talk to Dante and wait for him to give you 5000 eddies
4. Kill Dante
5. Take Ol' Reliable from Dante
6. Leave the laboratory and tell Mr. Hands you have the data
7. Deliver the data to the dead drop and wait for a day to receive 5000 eddies
