A group of earthlings scientists arrived on the only open planet in order to study the remains of an ancient civilization, which they discovered deep under water. You will be in this group in the game Collecc 3d. Your character will have to sit in an underwater bathyscaphe and dive to a certain depth. On the left in the corner there will be a map of the underwater bottom, which will show you which direction you will need to swim. Use the control keys to direct the movements of your underwater vehicle. There are many monsters under the water that will attack you. You will need to fire at them with the help of weapons installed on the boat. By destroying monsters you will get points.
