I am looking for the game that I used to play in here
I remembered:
The game started on the spaceship. People on the spaceship discovered the alien liquid stuff and brought inside on the spaceship. Unfortunately, this liquid escaped and then, they infected all the robots nearby and turned them into killing machine. Hopefully, this robot (the player) was the last robot of the spaceship can help survivors to escape the spaceship and return the Earth.
The mission:
The player would protect the base in front of the game and enemy from the portals will escape to kill us and destroy the base in the center of map.
I remembered that
We can upgrade the gun. We can install machine gun. We can upgrade the protection for the base.
I just remembered like that but I cannot find out the game of the game.
