Any intention to add more FPS gadgets, things like deployable shields or sentries?

Yes. A lot more gadgets are going to be added. Currently, we're working on different types of mines, like a proximity mine and a laser trip mine. So you could basically mine up your ship so no one comes and steals it. Deployable shields, yes, we're also working on that: something that you would place down and it would create a barrier. Also something that resembles a riot shield. So imagine pushing up an objective or storming a base with the riot shield dude at the front and everyone hunkering down behind him. And deployable turrets are also in the works.
