While the Microsoft Windows versions feature mainly 2D-animation and menus, the Dreamcast version mainly uses 3D models for the player, as well as 3D environments and the millionaires the player beats up in 3D, rather than 2D animation in the PC version.
Gameplay
The objective of the game is to answer multiple-choice questions correctly, by using a buzzer to answer. Following this, the player assaults another player's character. The objective of the game is to assault another player sufficiently so that they drop off the game's ladder, a parody of the real show's question ladder. The last player is the winner.
Lifeboats
Like its more serious (and non-violent) real-life counterpart, Who Wants to Beat Up a Millionaire gives the contestants "lifelines" (also known in-game as "lifeboats") to help them out if they get stumped. The three lifeboats are:
One or the other: Eliminates two incorrect answers, analogous to the 50:50 lifeline on the real game show.
Pass the buck and chicken out: Give the question to another contestant or swap the question out for a new one, analogous to the Switch the Question lifeline on the original show.
