I like the jacky's idea. Well, placing turrets in bases/safehouses/tents will make them really useless. But for example you could have 2 slots or 3 in CAPTURED TC town for placing turrets. And the rest could be like jacky said.
Also it would be awesome to see mechanical companions in game. Like mechanical dog, or some simply machines(all craftable) to killsome ones(alternative for muties maybe?) but in balance, not to make them OP.
And the energy systems in turrets/mechanical followers could be like this:
- they eat like 50 energy/minute.
- energy cap e.g. 2000(16 minutes with ,,full battery'')
- SEC would give 2 energy/unit, and MFC would give 4 energy/unit. There you'll have to get 1000 SEC to fully load a turret/companion for some time and 500 MFC. I think that's a fair idea.
