If both players agree, weapons will be stripped, players will have super armor and 200 hp for 5 seconds, then after 5 seconds, remove super armor and bring back 100 hp.
When the knife match has begun, the players have 30 seconds to either kill or hurt eachother. if one player has less hp than the other, that player will die automatically when 30 seconds is reached.
But the server can only ask the 2 last players if there were more players on the server and alive. if 1 player is on the server, and 1 joins and those are the only players on the server - do not ask for knife match. there has to be 3 players.
