Ubisoft has unveiled a brand new shooter which is played using a special laser gun peripheral - Battle Tag.
It was demoed at Ubisoft's E3 conference by a bunch of developers and models, who ran round the auditorium shooting each other. They were wearing harnesses to which the guns were attached via cables. Laser Quest for your house, basically.
Data from shooting matches is transferred to a PC, and the computer will keep track of what's going on wherever you play.
