Building upgrades
Once per day, certain
Construction Sites can be upgraded free of charge (without
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...).
Note: If 2 upgrades have the same amount of votes, there will be a selection process:
- The building that is more upgraded (has a higher level) will be upgraded. For example, if at Day 2 of your town you have search tower and watch tower at 20 votes each, but have watch tower at level 1/5 while search tower is not upgraded (level 0), then watch tower will be upgraded.
- If both of them are at the same level, then the building which reached that tie-vote first will be upgraded. For example, at 10h before the attack (Day 2), watch tower has 20 votes, search tower is not built yet. (Workshop was upgraded on Day 1). Then, at 9h before the attack, search tower is built. By 5h before the attack, search tower has 20 votes. However, by the time the attack comes, watch tower will be upgraded, since it reached 20 votes first.
