For a few months the Colombian government detected a formation of UFOs in Jupiter approaching the earth without any contact with the earth, during those months they built a cannon that shoots energy balls to protect themselves from a possible invasion.
UFO´s are attacking Bogota DC. Your job is to destroy them. Use the touch to line up the cross-hairs on a UFO to lauch an energy ball. The Red UFO will stop when the screen is touch; this UFO is worth 1 point. The Black UFO will keep moving and it is worth 4 points. The scoring will change as the game progresses.
The UFO´s lose a point for each point to get. They gain a point every 3 seconds, and point when you miss.The game is over when a UFO lands, or if their score reaches 50.
The plasma cannon is not very precise, but it is very powerful, with a single impact it is capable of destroying a UFO. Try to calculate the shot and see how the energy balls go to the different areas of the screen, also take into account that when the UFO goes very low they are not easily hit.
Your mission in this fun arcade is to stop the destruction of Colombia and the world.
