Tomahawk 777

a sega mega drive/genesis remake of an extremely obscure arcade shooter "Tomahawk 777" created by Data east in 1980. this is a very simple underwater game where you control a submarine that moves in eight directions, not just left and right. there are enemies on top, that can fire bombs and divebomb you. there is also a unique water drain mechanic, that is triggered after an enemy hits the seabed.
