Pingu:

 1 the combat knife. I have seen a really obvious facked screenshot of this when it was supposedly going into halo2 but have heard nothing about it in halo 3 got a screenshot you can show us?

 I've seen a Halo 3 supposed screenshot of the combat knife (in a magazine), but to me it looks more like a handgun. What i want to know, is why they would put in a knife, when there is already the melee option? this is the picture:

 well at the moment i cant find it, but i saw it in a magazine, lemme describe it to you so that hopefully you'll recognise it if you see it. There is a lot of fire in the background, there are other Spartans in the background but its a multiplayer screenshot, cus there was only one campaign screenshot. Anyway, the closest one has something on his leg, either it's a handgun or possible the combat knife?? i dunno.

And the double-barrelled shotgun, well i wasnt sure what it was but i think it is a shotgun, but it looks different. In this picture the Red MC is holding it. BUT in the background you can see a shotgun being blown into the air by the fusion coils. The light on the left side of the gun weilded by the Red MC cant be seen on the other shotgun (the one in the air in the background to the left) because it shows you only the right side of it. ANYWAY i dont know what its supposed to be, but it does look like it's double barrelled. I also think the nearest Blue MC has it on his back, but it's cut off by the end of the picture.
