Turns out you can play with Engineer units on the battlefield like this

Turns out the buildings on the map aren't just destructible, but you can actually use the 'repair tool held by Engineer units' to set up various types of defensive structures. Did anyone else just find this out recently, like me? For those who didn't know yet, feel free to try out this playstyle together. Personal tip: When setting up defenses, the repair tool turns into a hammer and you need to hit the target three times to successfully set it up. Another important point is that while the Engineer unit is holding the repair tool, their vision will be blocked by the defensive structure, so be careful as enemy gunfire might be aimed right at you. Pay close attention. Since you've read this far, why not give me a 'Like' to support me? Thanks for watching.
