GORY FUN !!
In Madworld, there are various fun bosses at the end of each level, Deathwatch mini games, and fun sub-vosses. Gameplay/controls are really easy and smooth. The overall game is really short; around 8-12 hours. Voice acting is smooth, and the commendators that you'll hear through out the game will create laughs or at least a smile.
Pros: Fun, never gets old, deathwatch mini games, commentators, voice acting, bosses, aliens, controls, the black and white design, and the game gives you room to do your own creative kills.
cons: Cheap story, and short.
