Dinosaur Staircase Mission – Break 5 Barriers to Find Indominus Rex!

I made a staircase with 5 barriers and put Indominus Rex at the very end. There are quite a lot of dinosaurs in this one, both normal and modded. I also added some other units to try the same mission. They need to break the barriers to get down there, but I'm not sure how many can actually make it through all five. I tried a bunch of different ones in this video.
