ALSO ALSO ALSO: think you could add alien gun turrets and lasers maybe with a production type of upgrade?
as in: gun turrets >to> alien gun turrets require the already built gun turret being coated in some alien plate and maybe some ore around the base ?
to force use of the ore as well as the plate
you could also make the hp regen based of your research and the 'Armor/Health' of the turret based of number of plates used ie: 5plate for 2x hp / 25plate for 5x hp
but that setup may require minor visual changes to distinguish the upgraded from normal o.O
or even just a small color switch toward purple for the fully upgraded ones :)
That's a good suggestion. There have been complaints that there's too much biomass and not enough to uses for it. As things are, I'd have to have separate graphics for each tier, which I don't want to do, so all the tiers would be visually the same (which is fine since you wouldn't be able to control which tier you're making anyway)
I could probably have costs increase based on tech level. It would be kind of hack-y, and I suspect there might be issues with assemblers
