We finally have our newly designed towers and they are WA~AY more engaging than the old towers. :D
So the ancient debug towers from another era had 360deg vision and could shoot through walls. The new towers obey proper line-of-sight (LOS), have a reduced vision and CAN’T shoot through walls. Base layout really matters now when you get attacked.
I also found an unexpected use for our T-junction corridor pieces. “Makeshift roach-motels” to bait enemies looking to come inside. :)
