It's been confirmed that the Doomsday Heist Acts Base in-game money payouts includes these amount: Act I: $650,000. Act II: $950,000. Act III: $1,200,000.
In the same way, can you do a heist with 2 players?
Only the first heist can be played with 2 players. All of the other online heists require more players.
Further, how long do doomsday heists take? The main missions of the Doomsday Heist are broken down into acts, which are story-based missions leading up to the payday mission. The Doomsday Heist has you going through 12 hours of content, with Act 1 having you steal ambulances to get inside of places in aims of targeting data in an IAA base.
At any rate, can you do casino heist setups solo?
The setup is next to impossible to do by yourself. Especially if you have to get the power drills. Sadly it seems that unless you have a lot of friends to play with, GTA Online is pretty much useless. You'll find yourself having to buy shark cards all the time like myself.
Can you fail the casino heist?
You pay every time you initialize it, after which you can fail it as many times as you want until it's completed.
