Despite the fact they generally sit on the mantlepiece as a decorative reminder of where one's interest lies, replica weapons are a big business and gaming enthusiasts are an eager audience to target.

Fans of Valve's Portal franchise are the latest group in sight. They're being pitched with this 1:1 scale model from the series.

The Aperture Science Handheld Portal gun, from popular Japanese replica manufacturer Neca, won't open holes through your walls, floors and ceilings, but it'll still be a blast to own one.

It even glows blue and orange depending on which space-hopping door you choose to imagine yourself creating.

The Portal gun can be yours for ¥16,000 (£131). The company started taking advance orders this week.

That may seem a lot for a weapon that would struggle to cause any kind of damage, but you can bet your bottom dollar that it could be used to startle any burglars into leaving a rather smelly DNA depositary behind as they dash for the window in which they entered.

Or maybe not.

The Aperture Science Handheld Portal Device starts shipping in April. Holy moley. ®
