I think that friendly fire should be removed (unless you blow yourself up) because in the past people have used friendly fire to kill you and then steal your weapon and some people troll and will kill you in the lobby so that you can’t stand on the pad for the game to start. Some people will use friendly fire to throw a game. Also, if you fail to revive a teammate because you don’t notice them or you can’t get to them until the wave is over, they will use friendly fire to kill you and intentionally not revive you. and I think that every quest should have checkpoints. Or maybe even having a difficulty selection, like easy for new players and hard for challenge seekers.
