WARNING: This mod is only useable if you have the Mad Scientist Mod activated, unless you want to alter the files yourself to make them compatible otherwise.
I've always felt that the defense platforms were limited in usefulness, so I've changed the defense platforms for all the factions to be considerably more useful. The damage is heavily frontloaded, so they hit hard, but fire slow. I've also more than doubled their range.
(I've also changed the damage type of the TEC's Guass Railguns to missile damage so the damage can be upgraded to keep them in line with the other two factions. That means upgrades that previously enhanced the guass railguns will no longer serve a function, ignore them.) The railgun animation remains.
Don't feel like building a starbase just to keep a few pesky purge vessels out of your planet? Build a few defense platforms and watch them turn to dust!

Installation: Simply download the RAR file, and extract the three files inside into your Mad Scientist's gameinfo folder. When it asks if you want to replace the files, click yes. If you want to be able to revert the changes in the future, I suggest you make backups of the current files.
