Online tank games include "Island Clash" from ArmorGames.com and "Battle City" from Y8.com. "Island Clash" has players defend their ground against invading tanks, while "Battle City" tasks players with navigating a battlefield to destroy enemy tanks.
In "Island Clash," players attempt to win each level by placing cannons and other weapons along the enemy's path. Every time a player wins a round, the difficulty of the enemy tanks increases, but the power of his weapons also increases.
In "Battle City," players must dodge enemy fire behind brick walls and other structures. While moving along the battlefield, players can collect power-ups to make them invincible for short periods of time.
