Editors’ Notes

These cats aren’t for petting. They’re for piloting giant custom mechs.

Let down

You could do better

I love the game but not the latest update. The latest version put an entire game within the game and adopted the ticket system from the Halloween special. It’s increased the complexity because now you are playing the same game twice with different rules and outcomes. Why didn’t the cool new machines replace the base game? What’s with the tickets? Why aren’t there comma’s in any of the numbers 1,000,000? Why does the timeline for each set of even’t stretch further and further with each update? Why can’t I put six crowns on each supply box when the space is available for six? Why did we go from three sponsor boxes per day down to two? I haven’t any particular fondness for the algorithm that selects opponents for your team battles. When the game was messing up and placing people higher than me, I sent word. I wasn’t offered any diamonds, coins, nothing. I feel like I am cheated every time I sell parts because my coin count will move as I sell parts but each time I sell the last of my parts, the coin count goes backward and then returns to the same count that it was on prior to selling the part. The algorithm selecting opponents for quick battles also seems to have lost a bit of its touch. I would previously skip one or two opponents that were completely out of my league and now it seems that I am skipping five or more before running into a comparable machine. I’ve played this for about four months and I guess it’s time I find a new game.

Things are good but...


I fight people with mini guns, but now the mini guns are way too op. They don't also deal more damage than before but are much faster then they were before the new update. I get the you get ultimate parts from promoting to the next stage but where is my normal parts box? I think that is more convenient then the ultimate piece box. If possible I would like to have a standard crate and a ultimate part. That would work. Other than that the game is great and is addicting

The ultimate fights seem good and all but there is a flamethrower in there and not the normal fights? I guess it would be op but why not give it a try to see how it does. Maybe lower fire damage and make it take up more energy to be fair. This is only a suggestion so don't seem like u need to add it I think it would be a cool idea to add it and a good one

Thought of something that I would think interesting. I would like to see different music when in leagues and battle themes that are more engaging wham in certain areas like the beach or city. It’s only an idea but I am saying that it would be a great idea.
