I believe this would be a cool feature for both the tactical and zombie game mode. Think about it what do most shooter games have in common?Players can get downed or knocked. If there are no respawns, this would be good because it can give you a second chance. Maybe you could still use your handgun, kind of like COD zombies. In summary, I think this would be a great addition to this game.
Thank you for your time, and I hope you consider this feature.
P.S: the game is looking great so far, keep up the good work.
