Helldivers 2's always-on friendly fire makes for excellent playground humour

When it comes to co-op shooters and most other multiplayer games, it's often the case that friendly fire is switched off by default or there are endless systems in place to make it a punishable offence. In Helldivers 2 it isn't actively encouraged, nor is it punished. Accidentally vaporising your teammate with an air strike is all a part of the campaign for democracy and freedom, a hilarious byproduct of human error. I gushed about it in my review, and cheery RPS fanzine PC Gamer wrote up a quick piece on the specific ways it eeks out silliness.

But comedy isn't just accidental in Helldivers 2, oh no. I think it encourages playground behaviour of the worst order: smacking your mates into things.
