Building upgrades

Once per day, certain construction sites can be upgraded free of charge (without PA or resources) : this is called the project of the day.

Just before the midnight attack, the upgrade which has received the most votes is accepted and constructed immediately.

Each upgrade can be improved up to 5 times. Each upgrade brings various advantages (improved defences, increased water reserves, reduced construction costs, detection of zombies, special abilities...).
