Call Of Duty 5 : World At War
Banzai features a lot of underground caves, leading to a waterfall under the bridge. There are also a lot of ladders and wooden frames for snipers. This map also includes black rock, which can also be seen in Makin. This is most likely volcanic rock and this suggests that Banzai is supposed to be set in Peleliu Island or in Okinawa.
There is an excellent spot that can be reached by dropping down from the American spawn and going to the side of the tunnel. This works especially well on Domination as one will have a direct view of Flag B, while few players will notice that player.
