Orcs Must Die! Unchained (PS4) - We Can Rebuild It Weekly Challenge Guide (5 Star with Midnight)
This one can be pretty tough. You'll see me struggle with Midnight some (with her HP), but unfortunately it's not much different with the other Heroes. I managed a 5 Star with Stinkeye as well, but he can get a little overwhelmed with how many minions there are. I think Gabriella is probably the toughest, because she probably would do the worst against all the Earth Elementals.
The Challenge is only tough because there are just a ton of minions to deal with, and you don't really get anything helpful in terms of traps.
I set up my Barricades in the same way as I did in Docks at Eventide: block off the east side and try to extend their pathway as much as possible in the west.
I do try to put some Flip Traps down, but they have some questionable use. Since you do get an entire wave of Kobolds (Wave 2), and the next wave has a lot of Earth Elementals, most traps are not going to get much use on these toughest waves.
For this reason, you can probably just use whatever traps you wish, but putting down some Viscous Tar is certainly helpful. Do keep in mind though it does nothing to the Earth Elementals.
I ended up being mostly reliant on my Hero (and Guardians) to kill things. The only thing I would really recommend is putting up a decoy Barricade before Wave 2 (for Tubifore) and Wave 4 (for Orfum).
Gaeadin does show up in Wave 3, so you may want to use Unchained for him. If you can manage it, using Unchained again in Wave 4 would also be really helpful for all of the Trolls.
