Of all the new weapons I've proposed see the whole series (1-2-3-4-5) the only one that I'm sure is good, necessary, and won't upset game balance, is the Mini Multiple Fire Rocket Pod (MMFRP). I'll use this as the first design challenge to work out game dynamics.
The real life model for this weapon is rather common system used on helicopters and attack planes. One example is here (where the first image is from). Many people assumed that the Micro-Missile Launcher is supposed to be this weapon, based on the picture (see to the right, taken from Uncle Al's 2035 guide) and it's misname.
The model for the new weapon is the "Six Shooter" - the Multiple Fire Rocket Pod. The original rules set for a Heavy Rocket and the MFRP was like 2 HR's, but different. And, when the MFRP was introduced, so too were mini-rockets, and the MFRP was kinda like 6 of those.
- HR = dam 3d, 2 DP, $200, 100 lbs, Sp. 1, 2" burst
- 2 HR = dam 3dx2, 4 DP, $450, 200, Sp. 2, 2" burst
- MFR = dam 1dx6, 3 DP (1/2 DP each), $450, 150 lbs, 2 Sp., 2" burst
- 1 MnR = dam 1d-1, 1 DP, $50, 20 lbs, Sp. 1/3, 1/2" burst
- 6 MnR = dam 6d-6, 6 DP, $350, 120 lbs, Sp. 2, 1/2" burst (price includes link)
It's possible that just halving the MFR will get what we need: MMFR = to hit 9, dam 1dx3, 2 DP*, $225, 75 lbs, 1 space, 1" burst. (DP = 1st shot destroys 2 rockets, second shot the final rocket and the weapon housing). Compare to 3 Mini-Rockets: 3 MnR = dam 3d-3, 3 DP, $200, 60 lbs, Sp. 1, 1/2" burst (price includes link)
It's possible, and more in line with the real world munition, that the MMFR should be 6 mini-mini-rockets, 0.5 dam per rocket.
Also, I guess for game balance the special warheads were forbidden for the MFR, but there may be a way of re-introducing them. For now, this is the prototype:
Mini Multiple Fire Rocket Pod, MMFR, to hit 9, dam 1dx3, 2 DP*, $225, 75 lbs, 1 space, 1" burst. (DP = 1st shot destroys 2 rockets, second shot the final rocket and the weapon housing)
