About

Mars 2501

Features
Read full description

Mars 2501 is a strategy game. It is a simple and fast game. During the game you build robots that destroy your opponents. The opponents are red and your color is blue. The one who destroys the opponent's Factory and Head building wins the game. As I said, the game is fast, you have to act all the time to defeat the opponent. There are three types of robots and each of them has a different firepower. Robot 3 is the strongest. Of course, there is also a bonus character, the Immortal. Killing him is not as easy as destroying the robots. And you can also build workers who repair buildings. Go to the building with the worker, if the building is damaged, it will be repaired. Movement is done by pressing the character with your finger, then he will stop, if you move in a certain direction, then he will move in that direction. Shooting is done automatically when the opponent is at a certain distance.
