WOTA is developed in Unity gaming engine. For those who say that the graphic is weak. Consider that this is a mobile phone game that is developed by one man without any funding whatsoever. So i can compare this game to SH5 iphone version and i can say that SH5 version is crap. This game is done for money, WOTA is being developed for love.
I hope that WOTA developer will earn a nice sum of money from this game.

Sadly i think that the market is not in right place because Iphone users like to buy "quick in, quick out" arcade type of games. I just dont see thousands of people simulating UBoat action on a Iphone.
God i hope i am wrong
