The ESRB rating for Titanfall has been announced as an M (for mature) rated game. The rating information synopsis revealed that the games content included “blood and gore, strong language and violence”.
The summary mentions “cries of pain, impact sounds, and blood splashes” and then goes on to depict graphic details such as “Some weapons blow enemies apart into small chunks of flesh” and that you can “crush enemy Titan pilots until they burst into chunks.”
For the Europeans among us, or anyone not rated by the ESRB, we can also expect a similar rating for most, if not all countries.
