Don't be afraid to step up
As many of us know, there are some teams that are VERY poorly composed, and some teams where the cooperation makes it seem like you're playing Darktide slaughtering everything in front of you with ease.
Well, I decided to take it a step down and chill out on a normal run which landed me on hospital, and it put me with a team that was NOT composed. I think only one other person used VoIP? We lost 2 or 3 before activating the air filter in the courtyard and when the processing unit started and the horde came, the remaining team wasn't even in the courtyard anymore.. I was just about to take early evac. Then I just decided... Let me see if I can rally these boys for one last good push.
Well, I VoIP'd and basically told them to rally up in courtyard and get ready to fight. Rally up and cover each other with these air filters. Cover cover cover cover. And by some fucking miracle, the team slowly started to get cohesion. The dude on the other side of the map was back and giving cover to another person carrying the filter - it was glorious.
After that, I basically said next part is standing and fighting in the square etc etc (if you know the hospital map you know the chain of events) and I just said "stick together, STAND AND FIGHT INNNNNNNNN THE SQUARE" I said that condescendingly because I have previously had teammates just run away.. well it clicked and we actually had a surprisingly big horde attempt to get us which got cut down fast.
At this point the team went from barely hanging on and almost dead, to full health, stacked, and unstoppable. Couple people went down at the very end in the morgue, but we picked them up and finished objectives, and successfully extracted with no more deaths.
Playing with strangers as a solo can sometimes be an infuriating experience, but sometimes all it takes is just one person to just rally people and coordinate. Just being that "voice" in a game where not everyone is using a mic can make the difference between things going south right off the rip, to the full lobby just death balling everything in front of them by just ONE voice.
