There's a lot of programming involved in making this weapon. It certainly isn't impossible but to do this from scratch without any knowledge of the game engine ( like BtAxis says this weapon ( specifically the ammo for it ) requires some form of AI and it should not always hit the target, it should have a small "internal failure" of something like 10% which would make the weapon dangerous to use , and only considered after tactical consideration ). Yes, the maximum ammo per squad should be limited to 2-3 , don't want USA-type warfare out there. I will wait for a few more people who would like this weapon, maybe we can then organize something.
Aniwae, this would be a very complex weapon at this stage, considering:
1) A complete entry would have to be made.
2) Graphics would have to be drawn. (and rendered)
3) Combat animations would have to be made.
4) Descriptions of the weapon would have to be written.
5) AI scripts would have to be created.
6) Tweakings, effects and i have not touched on the immensity of the sequencing of such a script.....(or scripts).
I would rather the developers at this juncture, to focus on debugging, on fine-tuning the already-existing weapons and features, and well, get the rest of the time on finishing the already approved projects.
Maybe if u would want to create such a complex weapon, (i am not discouraging suggestions for simpler-to-programme weapons like those of laser rifles, coil guns, etc), maybe u would want to write up some of those 1 to 6 points and commit to developers to have a look?
PS: I am not being a wet blanket here, nor discouraging brain-storming, but maybe we can consider for 2.4 development or even version 3 (aka future developments)..... definately not at this juncture.
