The game Thunderbirds stars Alan, Tin-Tin, and Fermat, three children whose guardians are part of the International Rescue team. The player takes control of all three children as they go through training and are then forced to travel around the world to save members of International Rescue from an evil villain known as The Hood.
The game takes place in various locations such as the International Rescue island, Africa, and outer space. Each of the three characters has unique abilities that the player must use to solve puzzles and advance through a level. Alan can use his strength and jumping ability to overcome obstacles, Tin-Tin uses telekinetic powers to move objects, and Fermat can hack computers and roll through holes.
The gameplay is primarily composed of solving puzzles from an overhead view, with occasional flight action sequences where the player can control one of the Thunderbirds vehicles. The game requires strategic thinking and problem-solving skills to progress through the levels.
