A little test that I threw together to test out using BM’s assets in hammer. It is pretty fun to play around with, too

If you want to download it, you can get it here.
Also, there is a bug with the HECU button where when you press it, the button-pressing animation happens with the scientist button, not the HECU one. The HECU still spawn though!
Have fun with the map!
Why did’nt you add the mortar and the gargantua and the trainsystem TOW 50.cal etc…
I didn’t add any weapons that you don’t “pick up” and have ammo for, etc., because this is only a first test. I wanted to see how to add basic mechanics.
