Bonanza Bros.

Get ready for an adrenaline-fueled mission alongside Mobo & Robo, whose lazy TV night turns into a high-stakes heist when a shadowy stranger interrupts the broadcast. Tasked with retrieving a series of mysterious items from ten heavily guarded buildings—and with only three minutes on the clock—your duo will have to knock security guards unconscious with limited ammo, slip past alarm systems, and outsmart the opposition. Fail—or get caught—and a $100 bounty is yours for the taking, so every second counts in this pulse-pounding race against time.
