if there is a sequal, i think that when you go back into the game you should start with the coal and gold statue etc and have to use them at some point in the sequal :)
actually daletvak1114 is kinda right with the clusters, when u start ur bomb that you drop is normal, but when u buy cluster bomb and the more you upgrade the more clusters come out, a cluster bomb is a bomb that when it explodes smaller bombs come out.
i agree with web smurfer, i think she did, and i managed to complete liberty island with the Nato sniper rifle and 2 assault rifle, my shooting survivers had sub machine guns and like 200 ammo each, u don't need to use the china lake, although it is fun to use
good game in middle i accidentally went to kongregate home page and had to start again.
they should also make a new one but hack and slash and were u do quests for people as a sequel
