Read third paragraph on how to save money from them stealing it!
Don't spend money on their game! You will lose it all and gain nothing! Save your speed travel money for when a plane crashes! Then use all your travel to get all the wreckage bags, usually you can get some guns. I bought 10 weapons packages and got one gun! One gun out of 10 packages! Useless on bunkers! BTW, mini gun is useless, stops shooting as soon as you adjust angle and then takes seconds to start firing again! Get killed every time you use it! I also believe the "players" that come kill you every time you're opening a box or looking in your bag are computer generated! Why? Because when zombies are attacking you and another player starts attacking you, the zombie never attacks the other person, even if they are five times closer to it! Play smart and make these rip off artists create a fun game for us.... for free! No respect for developers who make you spend money and then it ends up being useless! RIGGED!
The review that was below me was obviously a developer's review! Really? We should be happy we paid money and then you give us useless crap?! Yeah, I bet a customer said that! It's ok that anything besides guns is useless in a bunker?! Meaning you can't beat it unless you buy guns! I bought ten packages and got one gun! It would cost over $100 to beat a bunker at that rate! Yeah, I bet a real customer said that! Fake reviews from the developers for 5 stars!
Do not waste time on the bunkers! If you do not have machine guns, you're wasting your time and will get no where! If you do play bunkers, always store your coupons in storage before going out, otherwise, if you die twice before recouping them, you lose them all, meaning the entire bunker was a waste of time and you get nothing out of it! Again, DO NOT PLAY BUNKERS! I opened every door, killed every monster and it led nowhere. There was one door left and a machine to touch but surrounded by poisonous smoke. I went in in full swat gear, ten med packs, a mini gun, and two machine guns. Guess what? I automatically died! And lost everything and now I can't get to it! Good bye $40 (the amount I paid to get all different gear)!
Play for free as a kill-time game, don't care about getting anywhere, because no matter how much money you pay, you won't get anywhere besides slowly building stuff. I spent quite a bit of money at first, but realized spending money and not spending money made no difference in the game play (considering what you buy is either useless or gets lost). Thanks developers for creating a game I can forever play for free!
What is the point of allowing bunkers if you can't beat it until you're at least Level 64? The whole game is rigged this, there are so many things they give you, but you can't use until much later? Why? To get you to spend money! Hey developers, did you see that I was spending quite a bit of money before, but now none? That's because I realized spending money is useless and gets you no where. So now I won't be spending my money to play this game! Thanks for creating such a great game I can play for free for the next couple years!
