hunter freezing

I just got hunter the reckoning yesterday and i m at the end of the mourge level and it keeps freezing i have tride 2 get by it 3 times and every time it just locks up___ i rented this game about 3 weeks ago and the same thing hapend what do i do is there a defect in the game should i bring it back and get a new copy????

You should get your Xbox checked because if the same thing happened with 2 different Cds(one rented is more common to get frozen than a new one) there is a problem with the console.

got it 2 work must of had dirt on it or somthing
