The ESRB has now rated Mutant Football League: Dynasty Edition. This is an updated version of the game that came out last year. It should add a lot more content than before.
Anyway, the ESRB has rated Mutant Football League: Dynasty Edition as M for mature players over the age of 17 years old. The content descriptors says the game includes: “Blood and Gore, Drug Reference, Mature Humor, Strong Language, Violence”
The rating summary says: “This is a sports-action game in which players engage in arcade-style games of football with monsters and mutants. In addition to calling plays and assigning skills, players can use a variety of attacks to kill their opponent’s team members. Characters can stomp on opponents after tackling them, and use weapons to bludgeon or shoot opponents; one special attack allows players to use a chainsaw to plow through several characters. Gameplay contains frequent splashes of blood, as well as decapitations/dismemberments with certain weapons. In-game commentary contains frequent instances of mature humor, sometimes suggestive/sexual in nature: “Well if you are into humiliation and scatological fetishes, this Burns loss was right up your alley”; “These teams couldn’t score in a brothel”; “I’m so quick, I should be endorsed by premature ejaculation”; “Brick’s was almost involved in a threesome but his hand fell asleep.” Some commentary also contains references to marijuana, pot brownies/cookies, cocaine, and meth. The words “f**k,” “sh*t,” and “a*shole” appear in the dialogue.”
