I'm not sure if these were a very recent addition or if I've just been out of the aurora isles / jelly farm type levels for a while, but I ran into a curious box with the energy logo on it, "5 energy to activate this device". Normally I avoid wasting energy on anything except a loot-door with more than two red chests behind it, buuuut this was a new thing, so.. plink-ka-chink in goes my energy.
And then this laser cannon, slightly bigger than my entire self, pops out and proceeds to take its time vaporizing all of the jellies. Which, was nice for me since all I had with me was a rigadoon and a sun shards (I really need to read the gate maps more thuroughly).
Would I activate this thing again? Probably not. Seriously. That's my energy we're talking. I wish these things ran on crowns instead.d
Am I glad I activated it this one time? Yeah. It was pretty fun to watch...
Oh, also, when I went into the adjacent room I found out if I shield-pushed the enemies close enough to the previous room, the still-active laser turret would notice them. Eehehehehe.
The laser turret is definitely fun to play with once, or if you're down deeper than you should be with your current equipment, but I doubt I'd ever make a habit of using it.
