This map is obviously heavily influenced by Doughnut--one of my favorites. I believe, however, this map has plenty of significant changes to allow for a map experience different from but as good as Doughnut's. The major pickups and vehicles have a similar layout and same quantity to that of Doughnut except I added 50shields to each base.
The major difference is the shape of the map. Gyre is perfectly round. Another change is there are many more foot paths on this map at all different elevations. There are jump pads to assist your ascent to higher elevations as well. Manta runs are now easier to do because the flag is not in a smallish structure. Scorpions spawn on each flag flank, though, so defending the flag from Manta runs should be rather easy if someone chooses to do so.
I made a few more changes since we played the map in the PUG last night. I had accidentally forgotten to light the room in the middle of the map where the Redeemer is located, then fixed it in the next beta, but after seeing the fix, many requested I change it back; therefore, I have darkened the room again. It is not pitch black, but it is close. I added jump pads to help reach the Hellbender more quickly. I also raised the walls next to the Hellbender to give it more protection. I added a few blocking volumes to, hopefully, help keep the Hellbender from getting stuck when it drives off of its spawn ledge. I changed the jump pad emitter; the jump pads now look like the ones in Utopia. I turned off collision on the large flags to allow the Raptor more freedom while flying.
Here are some screenshots:
