needs to have a CO-OP option and prevent teaming in classic as it makes the game almost impossible for a single player to have a fair battle and chance to get top ten rank. I used to love this game in the last, I found I hasn't had any gameplay issues but like others the ads need to reduce/diversify, it's nonsensical to think someone will want to download a game after been shown it for the 20th time actually makes us less likely to download.

This game is a good one for making time fly by. I give this app four stars because of a bug that makes the game crash. It involves watching an ad to revive with a certain mass, in this case, 200. I would like this bug to be fixed in the next update for mobile.

After playing a round and watching through an ad, you will have to exit out of pop ups for over a minute before you can play again. Very clunky user interface and an overabundance of unnecessary interruptions just to play the game. There are many reviews complaining about the pop up quantity, as well as the timing of ads ruining the flow of the game, and the devs only ever respond saying they need ads for years, without adjusting the ads to a better level to make a better user experience AVOID
