So, in February this was announced, but I just found out about it.

SO, its a high quality replica plasma rifle. I thought it looked amazing. I mean, plasma pistol, plasma rifle (with the same overheating feature), and the energy sword. I am sure they will make more weapons, I just wish the energy sword could propel you through the air, oh well. And then, the $20 replica carbine and battle rifles, I just wish they too could be used in the game.
