Jurassic Survival is by the same creaters as Last Day on Earth so if you have played that game you will find that Jurassic Survival will feel familiar as it uses the same game engine and maps but with a different style of artwork. Like most games in the survival genre you have to run around and try to stay alive, in this one it's dinosaurs that are the enemy as you try to outsmart them using just your wits and your knowlege of nature.
You control and move your character using the virtual joystick on the screen, the punch icon is used to fight back against the dinosaurs and the hand icon allows you to gather useful crafting materials. The first thing you will want to do as you explore this hostile island collecting crafting materials is to build a safe shelter that the roaming dinosaurs cannot breach. This will include constructing firm walls, adding spikes and placing traps around its perimeter.
Once you have built your base you will want to equip your character with a weapon that is suitable for battling and hunting dinosaurs fearlessly. This can be be gained by acquiring a weapon kit, or dinosaur hunting pack. As you explore the island you will encounter other survivors in the same positon as you and it's up to you whether you want to team up with them and be part of a clan or rely on your own instincts to stay alive.
