The Gravity Gun will go on sale on Think Geek in April for $150, but there will be a limited quantity. Like the Portal guns that sold out in just 30 minutes last year, once they're sold out, they're gone forever. To give yourself the best chance of scoring a Gravity Gun, sign up for an email alert now on its Think Geek page.
The NECA Gravity Gun is stocked with sound effects and LEDs, and a kickstand for all those times you're not acting out Gordon Freeman fantasies with it. Check out the full run-down on Think Geek, and if you're interested, don't forget to sign up for that email reminder.
