So far in call of duty we have seen many game modes but i can tell you about 2 of the new ones in mw3.Basicly in mw3 ther is a new game mode called kill confirmed and whrn you kill an enemy they drop a dog tag when you pick that up you earn a point like the progession point in domination but if an enemy takes that tag kill is denied and you dont get a progress point towards your leave comments plz.
