I've been trying out a few missions in "Singleplayer". WIP aside I see geat potential here. Missions feel immersive (until you die) and production value is very high. Nonetheless, right now it's not really worth playing this unless you got friends to play with. Respawn and lack of AI team mates ruin the gameplay and immersion for me. I feel the campaign would play so much better in SP had the 3 empty slots been filled by AI with high skill level, esp if they would be able to use revive/be revived as they will ofc die sooner or later. And having respawning enabled here be it SP or coop is to me just laughable and unnecessary.
tldr; PLEASE make a propper SP port for all of us who prefer offline play and allow us to disable respawning for MP (maybe you already can???).
