Zombie Farm 2

Zombie farm 2 is the highly anticipated sequel to Zombie Farm. It almost exactly like the original, but there are some minor differences, mentioned below.

Differences from Original
Zombies no longer mutate in the traditional method. If you wanted to make, for example, a Zombumpkin with a dragonfruit and onion mutation, you would have to combine a Dragonfruit Zombie and an Onion Zombie, and then combine the resulting Dragonfruit-Onion Zombie with a Zombumpkin.*(Has yet to be tested)
 * The value of brains is multiplied by 10. For example, the Speed Monolith would cost 100 brains instead of 10, and invasions would give you 10 brains instead of 1.
 * However, it is now significantly easier to get brains. Along with obtaining brains via invasions and brain packs, you also get a brain every time you level up, four brains if you play five days in a row, and can get free brains for watching 30-second advertisements.
 * The different farmer heads can now be purchased for 15 brains each.
 * Crops no longer wither. Instead of withering, they lose "freshness", and only sell for half of their sell value. For example, a tomato that lost its freshness would sell for 15 gold instead of 30.
 * Mutated zombies can now be purchased in the market.
 * Life force has been removed. There are no more lifeless zombies, and no more failed mutations.
 * The Mutant Monolith now halfs the grow time for the mutant zombies, and the Zombie Monolith increased the amount of zombies you can have on the farm to 20.
 * The Zombie Pot can now be bought at level 3.
 * There is now the "Silver Grave", which allows you to plant "Silver Zombies".
 * Silver Zombies include Zombee, Zombarian, Imp Zombie, Zombielocks, Party Zombie and Robo Zombie.
 * The level cap has been increased to level 45.
 * New plants and decors have been added that are unlocked between the level 41-45 range.
 * The Mausoleum no longer requires a rusty key to open.
 * Hunger has been removed and replaced with "Concentration". Now you can invade as soon as the inasion timer runs out.
