Asteroid Cowboy

We're in the year 2020 - Earth was destroyed due to the foolishness of an orange-skinned president. Mankind had to escape to foreign planets. You made it to a fertile planet near an asteroid belt. The first people there founded P-Town, and fortunately your old neighbor built a ranch where he offers you a place to live and work. You're responsible for protecting the ranch from asteroids coming too close. Unfortunately, all rocket-launch-control-boards were used to build gaming consoles (yep, it's really boring up there...), so you had to think about other ways. You remember the cheap remote-controlled laser-lasso (without a CE marking!) you ordered from a foreign Asian country before leaving Earth, and your cowboy adventures begin!
