Hate to say it, but this is nowhere as good as Duke Caribbean since that went out of its way to look like a new game with different weapons, new enemy designs, new locations, etc. This just looks like a typical mod that just happens to be set in DC.
I agree Duke Caribbean is wayyyy better. Maps in Duke it out in DC are really big, long and confusing especially if you are playing it for the first time. Not to mention some of these stupid switches are hidden and might take you forever to find. But it's not that bad.
