Wild Card condition for Raids
When reading suggestion, I realize a lot of them would be both intresting and would also potentialy unbalanced the game a lot.
I think most gameplay modification should be added as a "mod" for a specific map, randomly chosen when picking a map, with possibly multiple of them.
Among this "mod" you'll get things like :
Solo Only, limited revive for duo, stronger guards (Like 3 possible mod on guards), stronger traps, no need for valid path toward the genetic materiel but rather a builder validation, limited time to do the objective, etc etc.
Making all of this optional would increase the creativity, and add a lot of variety to the game.
