As you can see in the video, you will be able to see the different upgrades for the weapons from different eras. But it isn't the weapons that makes this video. Okay, who I am kidding it is what makes the video. But I like the comedic points of the video, which I won't spoil any of it as you will have to watch the video to find out what I am talking about.
My take: This game was a hidden gem on the show floor of E3, they were in a small room in the far corner of the show floor, and as I walked out from that appointment I had a feeling that this game will be one of those games that rarely anyone will know about except through word of mouth. The weapons looks good but how accurate will they be? Will it be good? Will it be a flop? Will it do okay? Will these weapons be a huge impact in history? These are question that won't get answered until when the game comes out on September 8th for the Xbox 360 and PC.
I also hope they keep the comedic aspect as they showed in the video.
