Newbie protection: during your first 30 min of playtime other players can't damage you (except your team). It ends immediately once you attack a player yourself or own a ranged weapon. The remaining time is shown on screen.
Spawn protection: after every respawn you are invulnerable for 30 s – attacking ends it.
Combat block: for 2 min after a fight you can't claim kits or open the skin box – building still works.
Fair-play protection: whoever keeps killing naked and defenceless players gets flagged and loses perks. The kill feed shows fair fights and unarmed victims; fair fights earn honour.
Streamer mode ("Friends" tab) hides names. Being AFK for 10 min gets you kicked.
