Rg-V2 Prototype
The Rg-V2 (Ray Gun; Version 2) is a non-canonical Wonder Weapon in the custom Nazi Zombies map "Insel der toten". It is similar in appearance to the original Ray Gun, but it has different colors, and is more powerful. The rays on the Rg-V2 are blue, but when upgraded the rays become orangish-red, similar to Porter's X2 Ray Gun. When upgraded, it is called the RG-115 and has increased ammo, as well as a very small scope that is similar to an ACOG, but not exactly the same.
