Dynasty thought this might be helpful for everyone in the LRSD. This is a weapons chart that breaks down the effectiveness of every Call of Duty: World at War weapon. (Note: When these guns are in the hands of Gymboslice they increase in effectiveness 100%.) The websites information are based off the PC version but I would imagine it is very similar to the Xbox 360 version.
They got tons of other great information here on the COD Wiki and they have more weapon charts and other helpful stats here at this Call of Duty Blog. Notice how the PC version doesn’t have the Gymbo Perk.
Thanks Dynasty for finding this great information.
