there is strength but no dexterity or intelligence, you should add those. also not a lot of ways to get items ya know having a zone with constant monsters to fight that drop loot would be a great way to get them, and maybe a item shop to sell and buy gear as well.
the weapon pictures should change as they do in the gear upgrade window. you need overall damage, XP, and Money modifiers. my guess would be do gain (insert name) after reset based on how many monsters you killed that run. which you spend to upgrade said damage, xp gain, money gain, ext, ext.
Game Mechanic is set agenst you ever time they take a city back you loose zombie population and when you take it back from them you get less zombies then you had before even with the upgrade. before too long you have no zombies to make money with and loose. the game is great but you should ether make it a game 100% fully dependent of time factor or an easy casual game that you can take as long as you want to conquer the world.
ehh color in most games usual goes common: white, uncommon: green, magic: blue, epic: purple, legendary: orange, and godlike: red. not that you have to use this but familiarity of other games might hook more people into playing this. Also + All Stats is a must on the high end gear not to mention unique gear is something to look into.
reduce mug to 10 sec CD, reduce dodge to 30 sec CD minus 2 sec per point, reduce adrenaline rush to 25 sec CD, change sinister strikes to 3% agility per point or reduce its CD to 4 secs, change sap to stun all extra enemy's n not just one.
you should really change rogues skill agile strikes from .6% agility per point damage added to each attack to 2% agility per point added to minimum extra damage so at 10/10 skill extra damage goes from 0% to 50% agility in damage to 20% to 50% agility in damage. this would be better cause one of the biggest drawbacks about the rogue is the lowest min damage of all classes its also the best thing about the rogue as they have the highest maximum damage of all classes.
you should add more books (Spirit Tome and Lexicon of Doom, some names if it helps) for the other spawns and a final book (Necronomicon: Increased speed of all by 40% and Decreases cost by 10%)
more land = more buildings if you want to get buildings you have upgraded stop buying land. no room for them means they use resources to upgrade the ones they have
this game is not as good as the first one, if a virus has no symptoms how do people know they are infected. also you don't get enough points to unlock much threw the course of the game.
