War machine doesn't do 637hp of damage at level 4 as it states and is useless to upgrade. Motility is hampered, cobra and AZM missiles don't do the dmg they say it'll do and cool-down is too long to use them! NEED TO FIX WAR MACHINE STATS AND PERKS! My character is at level 14 doing that dmg. Other than that, it's really a fun game! Love the visuals and is easy to play. I don't mind replaying levels to get the gold required for upgrades, but I can see why casual gamers can be upset with that.

Fun until you hit a level that is disproportionally hard(there are a few). I did buy extra gold once and I still could not beat one of these levels. I reset the game and it took away my extra gold. That might be how it goes but I think it's kinda BS. Like deleting your DLC cause you started over.Update: Truth is you don't need to buy gold unless you really need an edge or are just impatient. At first I didn't realize that you could replay completed levels as they are marked as "CLEARED". You don't get as much gold but at least you can still earn it. I got to the last boss more than once and had no chance of beating it and would restart thinking there was no more gold to earn. Wish I'd known before I lost the gold I'd purchased.

This is an excellent defense game that is challenging and fun to keep coming back to. Each day, I clear my cache by closing all apps. (Double-tap home button and then press and hold it for two seconds, and then close apps in memory). This results in loosing all the cash earned that day to purchase upgrades. The game is fun enough to keep me playing in spite of this bug.

The thing is the gold and oil disappear too quickly. I bought $9.99 for the gold and im on stage 25 the zombies are more harder than usual so its like telling me to buy golds again for me to move on. I'm stuck on that stage and wondering why, i upgraded all my units and power ups but it seems the zombies are more harder 2 to 3x than my hero and army. This version really hard for the players to pass on the stage were you don't have enough golds for you to upgrade your hero, unit etc.. Please make it balance. The zombies toughness, the gold and everything.
