The weapon fires 3 rounds a minute in real life-- and this is either with someone with you carrying the rockets or with you next to a container with rockets in it. That kind of weight is impossible to carry around, so it's a one shot deal- besides, it's way too powerful to just allow more than one at a time.
Now on another note- let's picture this-- 3 rounds a minute.. that's APPRX. 20 seconds per fire.. that means about 15 to 18 seconds to reload.. with prime conditions I'm sure. (ie reasons I stated above) so for you to wait that long in one spot just to reload the AT4, it's smarter just to find another one. And if you think you should be allowed to move around while reloading, than we're talking like 1 maybe 2 rockets per minute. Unfortunately it's not as easy a deal to reload like HalfLife's launcher is. We're trying to be as real as possible with our weapons (accurate reloading and firing animations).
Hehe- so in other words, no, the AT4 will remain a one-time fire and forget deal. Thanks for the suggestion though! Just be glad I didn't say 'no' and leave it at that! /infopop/emoticons/icon_smile.gif
