We have nothing but utmost respect for eli vance, for creating zero point energy field manipulator, most commonly knows as the gravity gun, which is a tractor beam-type weapon that was originally designed for handling hazardous materials, but, as alyx stated, was primarily used for heavy lifting. At its core is a substance that appears to be a xen crystal. The good news is that this coffee mug is not as heavy as the gun that alyx struggles to lift and you don't need an hev suit to wear it.
So drink from this mug and pay your tribute to half-life, one of the best games ever made and to that one free man - gordon freeman.
Oh and keep praying for half-life 3.
Let us know what you think in the comments below, which are the most epic weapons in your opinion.
This half life gaming coffee mug is digitally printed using alien technology.
