In Darktide its always 12 Waves, at the beginning you choose a focus ( Indulgence) which dictates the character of the buffs you receive throughout your run. (think buffs to melee/ ranged, survivability, etc.) You receive a random minor buff every round in accordance with the Indulgence you chose at the beginning, and every 4 rounds you choose a major buff out of three presented to you (also in accordance with your chosen indulgence).
The mode is pretty fun, though the fact that there are currently only 2 maps lets it get stale pretty quick imo
If you mean the chaos wastes, it’s not that.
