a player selling your gun isn't a developer issue though, thats a system that is exploited by players. if they see that you are dying, will buy themselves a better weapon because suicidal doesn't offer alot of dosh. especially, if they have to compensate to keep the team alive, will run out of ammo or feel like they have to do your work for you. if you dont like hard mode or normal, i'd personally think you are bonkers. its nice that you have a chance to get your weapon back, and if you are a team player, often people will be courteous because they see that you have an impact in the team, and losing you along with your weapon will hurt more in the long run. .
try hard mode. you will see alot more thoughtfulness, because the players don't have to scavenge as much.
i'd like to see it where we can alter the amount of zeds to total throughout the game. we have wave choices, and we have difficulty, but nothing to alter how many zombies can be in the rounds, or throughout the game. one way to do this would have a boss activated round, where instead of choosing 4-7-10 round games, you can choose when to activate the boss round.
