Addictive game initially but has issues. There's no way of transferring your profile to another device. So if you buy a new phone you lose all of your progress and any ingame purchases! Most weapons are useless. Daily challenge gets harder as you progress so it is IMPOSSIBLE to get anywhere near your personal best. All my weapons now maxed out but only one worth using is rockets. The rest aren't powerful enough to warrant using them. Tried the game again after 12+ months and still no new weapons
