Music takes a big place in video game trailers, in my opinion. I mean look at the Dead Island trailer, that song made it as epic as it was. All the previous Gears trailers had songs that really made them give you the chills. More trailers need to focus on music, whether it gives you chills or it makes you want to kick some ass.
Gears Of War 3 will be out September 20th exclusively for the Xbox 360.
