Battle City

A persistent online world of tank-driving citizens and rival cities. Build, defend and raid in real time with other players.
- Build: Mayors place houses, factories, turrets, hospitals and research labs to grow their city and its income.
- Defend: Citizens patrol in their tanks, repair damage and fight off raiders.
- Attack: Teams raid enemy cities. A city can be destroyed when its enemies get through its defences.
- Team up: Chat with your city, with everyone, or whisper to one person. Cities rise and fall on how well their players work together.
- Orbs: Build an Orb Factory, carry an orb across the map in your tank and drop it on an enemy command centre to destroy their city. Bigger targets are worth 10 to 50 points. New small cities are protected until about 21 buildings.
