A PR stunt for Ubisoft's new Watch Dogs game backfired when a bomb squad was called to the offices of an Australian news station.

According to Ninemsn, a box containing a letter and a small safe arrived at its news offices. The letter instructed the addressee to check their voicemail, only that reporter didn't have a new voicemail. When they then punched a pin code into the safe, the device started beeping.

Ninemsn called other newsrooms to see if anyone else had received a similar package. "We did check with other newsrooms to see if they had received a similar package as we thought it was a PR stunt, but no-one else had.” Said Ninemsn's Hal Crawford. “We weren't panicked at any point, but given there was no note explaining what it was, we had to take sensible precautions."

Ninemsn evacuated staff and called in a bomb squad, who pried open the safe to reveal a copy of Watch Dogs, a baseball cap and a beanie.

At least the bomb squad didn't blow up the box. That would just have been a waste of good Watch Dogs. Ubisoft's public relations game has been pretty tight so far. Check out the video below of Watch Dogs phone hacking in real life. Watch Dogs is out now, read the review here.
