This is the place where you can find information about Utto - Ufo2000 Organizer.
Ufo2000 is the online turn-based strategy game inspired by X-COM : Enemy Unknown (a.k.a. Alien Defense) and X-COM 2 : Terror From The Deep. It allows to play battle (just like 'BattleScape' in X-COM games) : one player fight against other one through the official server or in hotseat mode.
Utto is a program which extends game's lobby and allows you to browse Ufo2000-related informations at one place.
