The Money Bundle is a free community melee weapon in PAYDAY 2, released on August 7th, celebrating 1 million members on the Payday 2 Steam community group. It is simply a thick bundle of hundred dollar bills bound together.
With extremely low damage (even lower than the Telescopic Baton), the Money Bundle's main benefit is its reasonable knockdown value if charged - and it can be charged quickly - and, of course, the comedic value of slapping cops around with a thick wad of cash.
Because of the Money Bundle's minimal damage capabilities, it is strongly inadvisable in every regard to use it in combat, though since the amount of knockback force it deals out per hit is rather high and its relatively fast charge time, it can be used as a last resort when an enemy gets too close for comfort, though again since it is so weak, using it against even a small group can quickly spell doom for the player. With this in mind its only real use is to get civilians quickly (and hilariously) on the ground to tie them up.
Players deal more damage per second with this weapon by attacking as quickly as possible, rather than fully charging attacks.
The total value of the money in the bundle is $10,000, as seen on the bank tape binding the notes together.
The in-game model differs from both the crimefest preview and the weapon's inventory icon; the in-game model is a fictionalized representation of the hundred dollar note, while the icon and crimefest preview show the real-life design.
In fact, previewing the Money Bundle in-game shows that the dollar bills are fake with an image of Dallas's signature mask on each note. An Overkill logo can be seen to the right of the right of this image, partially hidden by the bundle tape.
The words "The Grand Slap" and "Dallas" (with a stylized $ in place of the letter "s") are written on the bundle along with a drawn picture of one stick figure slapping another with it.
Bo Andersson's signature can be seen on the bundle.
When using the Money Bundle to attack, one can hear the sound of the notes unfolding like pages of a book being turned rapidly. Holding a charge also causes the bundle to "wave/wobble" audibly.
