Battle Simulator/Sandbox Editable - Beetle Uprising Suggestions

Alright so I got this idea after checking the post “Mystery Mode” and I remember saying I wonder if it's a Battle Arena or something around the lines of that.

I was playing the game today and I thought to myself, why not this game have a battle arena, customizable editable mode. You can choose some maps and plop down bugs and beetles with this, you could customize the stats. I feel like this mode could be helpful to the campaign since it can be very difficult and why not see 100 beetles vs 50 spiders? Either of those are good.

Again, this is a suggestion, but I feel like this game could do with a cool mode like this just like Empires of the Undergrowth.
