it seems to only be in h3 infection but the last man standing for the past 5 games has just killed himself over and over to beat the timer every time he was getting swarmed.he either jumped off map, used grenades, or used the environmental explosives. quite frustrating having a game drag on over this. either remove grenades and make explosives not respawn or make a suicide count as an infection. thanks for listening to my rant 
Please post in the relevant game forum for the game youโre referring to! Thank you.
