Things that could improve the Firing Range

A Gauntlet run.
While you can sort of make one yourself, I would like something a bit more dedicated.

If possible I would create a couple of modules that you could spawn in randomly, add multiple spawn points in these modules and then let the player choose the amount of bots, and level of them.
I'd suggest not having stric numbers but more like "low, medium, high" for the amount.
IF multiple paths are possible, even better.

A drone.

Have a drone fly around.
(other flyers like the dragons and cargo bots can be easier targets).

Moving platforms.

Since there are rotating towers in Olympos, maybe something like that could be implemented?

Timer/Kill count down.
This might tie into the gautlet, but having a set time or an amount of kills to work for while warming up might be something?

A smoky area.
A place where you could practice with the digi, or without.
