If its a ORIGINAL DOOM3 CD pack then u can either mail it back to the Manufacturer/Distributor (in India) giving details of the Date and Place of Purchase along with the CD key or u can mail it back to the original destination from where the Game is shipped.Do looks into the manual/support booklet to know more abt broken/damaged Cds and tersm and conditions for replacement (for free,if its a original CD version)
If u hv a pirated Cd version of the game,then jus buy another cd wich will hardly cost u sum Rs.50-Rs.60/-
Cheers n e-peace......
