Mobile / Round Robots / Sci-fi action / shooting game

[ElementUniYV]

This was a mobile game I played in maybe 2013 to 2014. It was a top view game, where you play as a round robot and you pick up weapons and shoot the enemy, who were also round robots. There were a variety of weapons and in the game, it appeared as boxes. There were multiple maps. Some kind of spaceshi[, fields, mansion, swimming pool? etc. The logo of the game was silver with a round robot with two blue glowing eyes. I hope someone knows this game...
