As the player advances in the game and upgrades his farm, new special buildings will become available.
We don't want to spoil the surprise and tell you which buildings there are, but let's say if you advance the farm enough having a fast-food restaurant chain, skateboard arena, bars and more will appear on your screen
Rare Defense Tank: when reaching a certain level in the farm, players will get the ability to mint a Tank NFT. This is a lethal tank with a machine gun and a cannon that will disintegrate your attackers on the spot.
The tank will appear under the headquarters menu for available upgrades and will spawn using mutant liquid.
