Shadow the Hedgehog

Due to the mildly violent nature of the game, the ESRB rating was, for a time, in question. The official ESRB website originally had the game rated as T, along with GameSpot, but the official site listed E-10+. The T rating was seemingly further evidenced, however, by the fact that, at trade shows where Sega showed off the game, they asked only those 13 and older to play the title. Early builds of the game even had mild swearing in them, and the game does include two mildly offensive words (damn and hell). For the English Version of the game, Sega took out the human's blood, changed the color of alien blood from red to green, edited the word 'piss' and put 'tick' instead (Sonic says this), and censored the scene when a GUN soldier shoots Maria, cutting out as Maria is shot and falls to the ground. Regardless, the ESRB website later updated the rating to E-10+, thus making it unanimous.

The G.U.N commander blames shadow for the ARK raid and has held a grudge for revenge for 50 years, despite being on-board as a child at the time of the raid, so he should know that G.U.N killed everyone. What is most puzzling about this is that he now works for the organization that ruined his life.

There are alternate takes of Shadow the Hedgehog saying the word 'fuck' every other line. According to voice actor Jason Griffith there is a hard drive of these files. He also had to record two different versions of each dialog line.
