To be able to unlock the achievement quicker, you first need to get $100,000 to be able to have dinner with the CEO!
If you don't want to walk around too much, you can use the pirated goat mutator. You can unlock the pirated goat by going to research dome on left from spawn and go in and use the 3D printer.
Then just lick a NPC with $ signs, keep pressing the
button and more should spawn. Head butt the lot of them and then rinse and repeat.
You can get money by smashing crates, hitting people with the money symbols on them and doing quests for people.
You can go for some of the other achievements before attempting this as you'll earn cash while doing other achievements. LIKE
$25,000 to follow my guide for all trophies(just under $1,700 each one)
$35,000 for the spaceship upgrade so you can earn money going for the blow up ship achievements.
$40,000 for the Test Chamber with a stack of money crates at top after finishing all chambers
It took me the best part of a hour to get $100,000 without mutators, but should make it faster than that with some of the above information I didn't know before.
Once you have 100k go to see the CEO and just headbutt him and then he will say "You're fired! !" then just go outside and hit/mash the
button(which will spawn in money crates) while pressing
to smash them as you go.(See below)
It's much faster to get from 100k to 1 million if you repeatedly hit
. This will constantly spawn the hover bike thing and explode it, breaking the crates as you spawn them (pressing
gets you back up again after the explosion). Thanks goes to Octobot Super for that piece of information.
Less than 5-10 minutes later you should have 1 million and you're done.
