For a 9-nuyen-card, I sure hope this gun is firing a rocket and I sure hope everyone is looking at how awesome it is!
I agree with you, I read this card as a "Get a turn free of damages". Thank you for confirming my interpretation. Too bad it stops as soon as the next runner begins his turn, hehe.
Really useful card in the Extraction mission, where we just want to survive those 6 rounds and protect the client. In the Crossfire mission, this card can be tricky though since the goal is to destroy all obstacles and having up to 4 obstacles in front of a runner can be lethal...
