Yes, it is starting again! NECA is putting up 100 P-Body Portal Guns for preorder at midnight tonight. They just announced a little while ago to follow this link to get to the order page that will open at midnight EST. The last one sold out really quick, I don’t expect this one to last long either.
Of course the P-Body Portal gun is a slightly modified version of the original to look like the gun P-Body used in the Portal 2 coop campaign. If you are reading this I am sure you already knew that, so now you know what to do as these are sold out everywhere!
I believe they will also be shipping soon as it is June.
