I would like to request an implementation of aliens who have a natural (especially melee) weapon, but can also use normal alien weapons like rifles and grenades.
I probably wouldn't be whining about adding new stuff when 1.0 is still requiring plenty of work, but this particular feature will be required for TFTD anyway (lobstermen), and I believe TFTD is considered a valid project in itself, just much less prioritized.
Why do I want this feature now? Because I want to implement Lobstermen to the current
X-Com.
I believe there is a logical gap in the alien races, basically there is no race that has really good armour value, which would require new tactics. But I'm sure there would be many other uses for this feature for the modders.
