How to Play Dragons with Rocket Launchers

About Dragons with Rocket Launchers, from BoardGameGeek:

It's a peaceful summer's day on Dragon Island... or is it? A case of rocket launchers just washed onto shore! Dragons with Rocket Launchers is a card game of frantically shooting rockets while fending off rockets coming in the player's direction. Each turn, a card is played affecting the state of the battlefield. When a Rocket Time card is played, all the rockets in play will move around the table and potentially eradicate some players. Be the last dragon standing to win Dragons with Rocket Launchers! -description from the designer
