Our take on Questerium: Sinister Trinity HD Collector's Edition

Players who expect combat to drive an adventure may bounce off when the investigation turns to puzzles and mini-games. The central tasks are to locate two children, stop the machine, and arrest the professor, so anyone looking for open-ended objectives may hit a wall at that fixed rescue-and-resolution sequence.

What is Questerium: Sinister Trinity HD Collector's Edition?

A meteor’s energy mutates the city’s plants and animals after Professor Gustav builds a machine with funding from the banker.

Playing as an investigator, the player must find two children left behind during the evacuation, stop the machine, save the city, and arrest the professor. The game includes puzzles and mini-games, quests, and 20 secrets placed in mysterious locations. Players can also develop a garden and unlock achievements. The story follows the fallout from the professor’s unauthorized experiments and the roles of three childhood friends: the professor, the mayor, and the banker.
