The concept has changed I really enjoyed 1 and 2 of this series. However, the concept of this series seems to have changed significantly. Car action is now a sub-game, and the main game is a gun shooting action game. Those expecting a similar game may be disappointed. The main game is fun, but the paid elements have become very strong. Monthly passes similar to those found in other games, merging the same equipment over and over again, and viewing advertisements to get rewards are implemented. Unless you pay, you'll be stuck in no time. I purchased a monthly pass and would like to play for a while, but I have one request and one bug report. First of all, if you have purchased an expensive monthly pass, it would be nice if you could skip all ad viewing. Next is a bug report: If you restart the app after changing the language, it will be reset to the default English. If you resave the language from the settings menu again, the language will be reflected.
