Finally got around to trying this game! On one of the Paradise servers, hopefully we're allowed to discuss other stations here?
My first experience was bizarre but pretty nice. I came onto the station very late in its run. I dicked around in the arrivals tool storage, trying to figure out how to do basic things. Ended up emptying a blue toolbox on the ground and then hitting myself with it, then dropped it but forgot that arrow keys move instead of WASD. In the midst of all this, a corticol borer slowly crawled under me. I noticed it pretty quickly but tried to move away using WASD and so was infested. The borer player was actually really nice! Once I figured out how to talk to them (and that people wouldn't realize I was infested just because I was talking to myself in the hallways), we had some talks. They used the possession as an excuse to give me a tour of the station, with random detours into bathrooms to make more worms.
Probably helping our budding symbiosis is the fact that despite reading about this game for literally years, I had no idea what a borer is. So I assumed that I was an antag and I had to do whatever the worm told me to. It was a good strategy, I ended up successfully escaping the station with the worm in tow.
Edit: Oh, and the worm actually didn't kill anyone. It possessed me and dragged an unconscious person back to sickbay, then successfully healed them. That person will never know what wormbuddy did for them.
