The reason sh4 so easy is because of the thermal layers if sh3 had thermal layers it would be an easy game to,so with a simple tweak u can make sh4 twice as hard as sh3 Open the Data/Cfg/Sim.Cfg ,in Sonar change sonar sensitivity from 1.0 to 0.05 (this is TMaru setting) Enemy Surface Factor to 120 and Thermal Layer attenuation to 1.0.Now go to Hydrone section and change the other thermal layer attenuation to 1.0,this will disable the thermal layers u most do this while on port .This is sh4 stock 1.5 i dont use any of the super mods.Now u must run silent and deep you can still get away if u know what you doing, sometimes you wont,the external camara helps,if you are commanding an sboat just hunt for lone merchants.I know this mod is not for everybody only for those who like to be challenge and deadcharge for hours below crush depth
for me this is the only way to play the game
