I didn’t get to play much, because of work.
But my general impression is highly positive.
I think the main thing that will determine success of this game mode is maps.
Grate maps with verticality for both sides.
interesting and more challenging objectives, that may require U5 to split in duos for instance.
If you don’t want to increase horde density, than you should increase length of the maps. Short rounds was the main pain point in alpha to me.
Versus has great potential in my eyes.
I’d say don’t afraid to experiment with it and go wild.
I wish you luck
