I think their approach to team killing is part of why the user base is so forgiving of team killing.
It is included in the training and baked into the game play by having generous respawn limits. There are jokes about it baked into the promotional materials. Everyone expects to be team killed on accident, so people tend to assume any team killing is accidental. People who might otherwise team kill on purpose will either get their fill through accidents or will not get immediate reactions that feed their trolling.
So by keeping the team killing in the game they have also defused a lot of possible trolling while also having people just accept it as part of the game, especially when non-player initiated features like turrets and backpacks are the worst offenders for team killing.
Finding it funny is a great approach, kudos to the devs.
Either that or the bugs just wander through and only 3 die.
Yesterday I saw a guy step on a bot mine, then another teammate went to see what happened and stepped on one. Then on the reinforce they both went back for their stuff… but at least the mines were clear after!
When I first started playing with my brother, I was shocked to learn that he was fuming for days when I called down an Eagle Airstrike on him. I thought it was hilarious at the time, but he was legit mad. Then after playing for a few weeks, he came to lighten up and realize that team killing is part of the fun.
But yeah, if you come from a game like PUBG where team killing is a mortal sin, it can be a bit of a shock to the system.
Last night I was the last survivor of my squad with no reinforcements left. I was trying to run to the evac shuttle. 3 giant bugs killed me, ending the mission. One guy told me to kill myself all in caps and to delete the game and he hopes I get banned and then they kicked me from the party. Not a super experience.
I don't like to team kill on purpose, but I do think it's very funny to drop an orbital J U S T outside the range of my friends occasionally to keep them on their toes.
Sometimes their toes are the only thing left of them.
(It helps that I only play with IRL friends and only with VC so I can warn them. But you know how it goes, you don't always hear the warning even over VC.)
I had a few matches when I first started where I was purposefully (no enemies around) killed right before extract. It hurt them as much as me, so I don't get it, but it was frustrating. Other than that, yeah I assume it's accidental. At higher difficulties no one is doing that as far as I've seen.
