I think it pairs well with the loot you get to chase.
Variations of S tier weapons is the way.
With the weapons they chose it will be repayable for a long while.
Honestly it didn’t feel as long as the playing time involved.
Thats a good indicator and it’s something they can build on IMO.
I forget how long into the 50 waves but I got a shiny Elsie headseeker roll drop.
The weapons and the way they drop are a big part of it. And the activity blends its gameplay aspects together very well and makes it feel that much more like you're moving towards something.
Yeah that's just something that you can tell probably led to more ideas while they were doing it. The way the rewards are handled in that mode could be expanded to something like comp (if its worth it) or even gambit and or other parts of the game. If interesting things drop like that then people will play the stuff in the game that's otherwise good as well. Even if its been around longer.
