RSO: Range Safety Officer

A one or two-player action game of dexterity. You are the safety officer for a rocket launching range. Launch rockets, fire their retro rockets, destruct short launches, and manage launch pads.

The solitaire game is juggling. You launch rockets, they come back, you fire their retro rockets, and land them on an empty launch pad. The object of the game is to juggle for as long as you can.

The two-player game requires two devices, connected via WiFi or Bluetooth. You launch rockets to the other player’s device. The object of the game is to mess up your opponent. Vary the size, speed, and quantity of rockets to surprise your opponent. You lose when your fails total 15 points.

Launch a rocket on a pad by flicking up. Soft launches, called undershots, stay on your side and flip sideways when they reach apogee. Tap an undershot to destruct and flip the rocket into landing orientation. Failing to destruct scores two when the rocket hits a pad.

Launches off the top of the screen go to your opponent, and fall from the top of their screen. Launching too hard is an overshot and scores one. Overshots arrive to your opponent sideways and your opponent must tap them to destruct them.

Tap an incoming rocket to fire retros. The rocket flips over and settles onto a pad. Failing to fire retros scores two when the rocket hits a pad.

In both games, after you start playing, you must not let a rocket land on a rocket. That is a launch pad disaster. All the rockets involved are crashed and score two points. In the two-player game, crashed rockets cannot be launched temporarily.

You play solitaire to set a new record time. Solitaire ends on the first fault. When the next game is ready, the screen turns green. Then on your first launch, the screen turns blue.

The two-player game does not pause when players fault. The two-player game ends at 15. The screen turns red, then green when you can play again.

The settings include a level of difficulty, and the number of rockets in play, from five to nine.

The full game is free for a three-day trial period. After that, you can continue to play solitary with five rockets. Or, from within the app, you can purchase the right to play with more rockets and to connect to another player.
