Sea Battle 2 is a virtual version of one of the students ' favorite games. If in the old days, the game required two pens and two sheets of paper, now you only need a mobile device on the Android platform and access to the Internet. The developers have done a great job of recreating the atmosphere of battles in the classroom, because the graphics are made in the style of drawing. In addition to the classic mode, you can try out others, which include the use of aircraft, underwater mines, cruise missiles and radars to search for enemy ships. All this adds dynamics and novelty to the usual gameplay.
