So, just out of habit, I usually kill zombies before trolljans when there's a room filled with both. Makes it easier to kite them around and get in behind them without having to worry about a zombie groping me while I jab at the trolljan in the butt with my pointy sword.
Today I learned that I probably shouldn't do that.
I was doing so well before that last wave spawned, too. Then I went down twice. *sigh*
Haha, yes, that happened on my first FSC trip. I was running around like a headless chicken and getting knocked around like a pinball. My teams usually leave one zombie alive, heal up, then try to take out the two Trojans that spawn as soon as they appear.
