Army Defender

Army Defender is an action shooter in which the player must defend his
base against enemy attacks by controlling a machine gun tower designed
to eradicate enemy waves. As the player levels up, the enemy becomes
more and more numerous and well-equipped. Attackers include soldiers,
tanks, paratroopers, helicopters, jet fighters, bombers, elite
commandos... Depending on the enemy type (red and green), the player
must switch between ammunition colors. The machine gun tower will fire
where the player taps the Touch Screen. Power-ups are made available on
a regular basis, when a super bomber delivers them onto the base. When a
power-up is retrieved, the player will be able to upgrade his tower
during a limited amount of time. Upgrades include flame-throwers, rocket
launchers or concussion grenades that will help contain enemy
progression.
