A world full of mysteries inhabited by a wide variety of creatures, including dinosaurs, legendary beasts, and organisms unique to this realm. Here, the protagonist must use their wits to struggle for survival against the backdrop of the great outdoors...! Gather various materials to craft tools and bases, tame creatures as companions, or live a quiet life of solitude—the choice is yours. However, death is always by your side: being mauled by dinosaurs, drowning in dangerous waters, dying from extreme heat or cold, falling from great heights, succumbing to hunger or dehydration, or falling ill from raw or rotten meat. Yet, for some reason, one can respawn and return to life in this world. First, you must prepare for survival: build a base, start a fire for warmth, cook meat or gather berries to satisfy hunger, and craft clothing. The world is populated by a massive number of prehistoric creatures that once existed on Earth but are now extinct. Most of these creatures can be befriended through specific methods, equipped with saddles, and ridden to assist with hauling cargo, travel, or combat. Making them your allies is called "taming." Legendary creatures like Unicorns and Griffins also exist, though they are extremely difficult to find. By collecting items called Artifacts found in caves and other locations, you can warp to areas where Boss creatures reside. However, these bosses are incredibly powerful; even a pack of Tyrannosaurus Rexes surrounding one could be wiped out in an instant. Some creatures have "Alpha" variants, which are significantly stronger than normal individuals. An Alpha Raptor can possess power rivaling a T-Rex. They are characterized by a red aura, so beware of anything glowing red. They are quite rare, making encounters difficult, but defeating one yields various rewards. Levels are set for almost all creatures, including yourself. By gathering materials, crafting, or defeating creatures, you can level up and increase your stats.
