Tip 1.Create a low-leveled account on different devices and play on it for almost guaranteed victories
Tip 2.Some weapons that are reskins or have reskins(exterminator and thunderer)actually have equal everything(grades,shooting speed,capacity)and sometimes,the cheaper one actually has more benefits,so buy the cheaper ones.
Tip 3.If low on cash or gems,play mini-games,watch videos,find the secret loot in campaign or play raids(monsters drop coins) or kill players for gems.
Tip 4.Three-cat spam more,it is not an offence at all in the actual game.
Tip 5.Complete as many battle pass challenges as possible.The tasks are usually the same every season.
