Trinity Fusion takes the user to the world of the future, where humanity has managed to achieve such a level of technological development to travel not only through outer space, but also into parallel universes. Now the best scientists of civilization are faced with an almost impossible task – to save all living things from an imminent catastrophe. The specialists of the research mission, after long-term observations, came to the conclusion that the environment is gradually falling into disrepair and will soon completely crumble into pieces that can no longer be reunited.

The leading role in Trinity Fusion is played by a representative of the scientific intelligentsia, who decided to delay the moment of collapse or prevent it altogether. She moves between realities, remaining with an identical consciousness, but inhabiting the bodies of characters differing in appearance and skills. There she struggles with the causes of problems and tries to neutralize them. The journey takes place through colorful two-dimensional locations with authentic graphic design and style. The protagonist will visit dark dungeons, futuristic stations and desert areas. The maps are crammed with deadly obstacles and treacherous opponents – they must be destroyed using close-range attacks and small arms. Comfort is added by the familiar mechanics of a classic platformer with a lot of visual effects.
