Human Invaders: Mars Defense

The invasion is coming — from Earth. You are Mars's last line of defense: a lone Martian cannon standing on the real Martian surface. Human lunar landers are dropping out of orbit wave after wave, and only you can shoot them down before they touch ground. • REAL NASA MARS PHOTOGRAPHY — fight across Olympus Mons, Valles Marineris, Gale Crater, the polar ice cap, a global dust storm, and the famous blue Martian sunset. Every backdrop is a real NASA image. • CLASSIC ARCADE ACTION — drag to move, auto-fire, dodge. One thumb. Sessions fit in two minutes. • A FLEET WORTH FIGHTING — scout landers, gunships, armored haulers, and the orbital COMMAND SHIP boss that aims for you and fights harder as it burns. • POWER-UPS — plasma spread, energy shield, dust storm, bonus salvage. • 10 CAMPAIGN LEVELS + ENDLESS MODE with a rising score multiplier. • EASY / NORMAL / HARD — from chill to merciless. Hard pays more. Free with banner ads. One $2.99 purchase removes them forever — optional watch-an-ad bonuses (like extra-life continues) stay for everyone. Prefer not to watch? A $0.99 pack of 20 extra lives has you covered. Mars imagery courtesy NASA (public domain).
