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.



*Decided to try it again. Yup, it’s still a scam.

I played this for over a week and was simply frustrated the entire time. Yeah it's a bit fun but when you cannot get a decent vehicle with decent slots to drop for days on end you will rage quit. I must have looted over five dozen vehicles and only one or two had even remotely decent slot placement for weapons. Oh cool I looted a legendary chainsaw that gets a bonus on titans! Oh well my last seven titans have had the weapon slots either on top of the vehicle or too far back to use the chainsaw, or they're just too weak and don't have enough power to use two weapons. This pattern repeated itself endlessly no matter how much I upgraded my halfway decent vehicles or how many different setups I tried. I ended up using a weird surfer setup to bulldoze or flip my opponents to the edge and wait for the level itself to kill them. Yeah so much fun... The game is basically there to make you watch 12 ads in a row to open boxes that are filled with garbage. Progress is painfully slow and the gameplay is just straight up frustrating. I really wanted to like this game but it just threw garbage at me so that's where the app ended up.
