EVE:WORLD is a free project that takes advantage of the Outerra engine's 1:1 scale rendition of Earth to bring you a planetary invasion simulator set in the EVE universe. Battle through enemy lines in everything from 10m drones to 18km Titans. Make a controlled descent through Earth's atmosphere to strike at targets around the globe.
Part of the Rudimentary AI update, turrets can focus on a target taking their position and rotation into account.
Like the lighting doesn't make this look absolutely real. I am begging you... full joystick support.
