UFO: Blackstorm shield
You pilot an alien ship with the ability to absorb enemy bullets and turn them into energy, which you then use for shooting and powering several buildings at your disposal.
Research alien technology to build 12 different facilities and protect the city.
UP: take energy from a building
DOWN: give energy to a building
Super awesome tips from the Developer:
-Losing is OK, when you lose you keep your money and can build a stronger city.
-If you run out of bullets: steal energy from the shields! (up)
-If a shield runs out of energy: transfer energy to it! (down)
