Tank Invaders: War on Terror

Tank Invaders: War on Terror is a vertical scrolling shooter with a twist: instead of seeing their ship, players view the action field from a first-person top-down perspective, tapping the touch screen on their devices to fire missiles against enemy vehicles and avoiding to shoot ally vehicles. Players take damage if the enemy vehicles are not destroyed and manage to reach the bottom of the screen. Boss fights are also featured, where players have to avoid being shot by cancelling enemy attacks.

A special kind of weapon, the OnFire mode, is charged with energy dropped by enemies when damaged. Once the OnFire bar is full, players can activate it and drag their fingers on screen to quickly destroy enemy vehicles until it is depleted. Completing objectives such as destroying a number of enemies or rescuing a number of allies grants coins that can be used to purchase upgrades (such as new weapons and shields), consumables (such as nuclear bombs) and different OnFire weapons. Temporary power-ups can also be collected during the missions and can be upgraded to last longer and have their effects enhanced.
