Possible upgrade modules could be for example:
- tier 1
--Range module +10%;
--Damage module +20%;
--Speed module +20%;
- tier 2
--Range module +15%;
--Damage module +30%;
--Speed module + 30%;
- tier 3
--Range module +25%;
--Damage module +60%;
--Speed module +60%;
For research there could be researches for the corresponding modules like with the normal modules.
And a research for adding module slots for lasers and for gun turrets, up to a max of 2 or 3 module slots?
Pro's:
- New factory's for making upgrade modules for your defenses.
- Getting new items to play with from your research.
- Gun turret gets more useful with the range module for its current short range lack over some enemies.
- It gives more variations on how to build defenses.
And if you want to go even further, the beacon could be changed to also allow for turret modules.
The prices and exact stats for the modules could be discussed.
If someone feels like making a mod for it now, please let it be known
