Base shields have been updated to be faster and better than before!
They use less power when being attacked by massive barrages and they in general take less damage from starships, for starters. In addition, instead of going straight to air, there are levels - they go from white energy to yellow energy to orange energy to red energy to air!
This makes it almost impossible to get shots through without insane amounts of weapons, or a very complicated bomber ship (which can be countered with multiple layers of base shields, at the expensive of more power usage). It also solves many exploits relating to, for example, water.
Base shields are now viable machines for defending your base! You can use them to save yourself from raids by your enemies. (Keep in mind, they do have a finite amount of power, so you will want to have some offensive defensive measures too for serious base defense).
For more information about base shields, remember that you can see them here.
"Most if not all of the primary ship systems are now on the wiki! Check out starship weapons, in particular. While there will likely be an official ship building guide as well as a combat guide in the future, for now those of you who like tinkering can start messing with ship building in whatever creative world/server you use."
