SENTINEL Descendants in Time is a gripping science fiction adventure set more than 1900 years from the present day in a rich pastoral region of our own future Earth.
In this quest for riches and knowledge, you can uncover the mystery behind the Tastan Caverns. As you begin your dangerous journey, you'll encounter a female sentinel programmed to guard the sacred caverns. Her dark purpose, however, may impede your progress through more than 20 puzzles. A built-in hint system may come in especially handy as the puzzles become more challenging.
Each of the game's eight worlds features diverse environments, ranging from snowcapped mountains to active volcanoes.
