Same mod, different name, The Galactic Empire, the Rebel Alliance, the Black Sun Pirates, and the Droid Empire, fight for control of the galaxy.
The Grav Well ability for the Empire and Rebel's Interdictors are no longer unlimited. They now last for 60 seconds before they deactive. After that you have to wait 20 seconds for the ability to recharge before you can use the Grav Well again. This is more close to canon, since the Grav Wells couldn't stay activate all the time. It was a Huge drain on power.
A good idea to deal with this is to bring two Interdictors into battle. While one recharges, the other can use it's Gravity Well Generators
