had one tonight...It started as playing a mod that doesn't exist: a co-op one where you choose between 4 classes with their own abilities and pick ups and hunted monsters through maps togeather...then it changed.It became a huge map,with real people trying to survive a Quake1 monster invasion,with a final battle in some giant cathedral with multiple levels and creatures to conquer,but you had to fetch certain keys from the surrounding houses.I was trying to help people open a safe in a trailer home while a shambler was trying to claw its way through a window when my alarm went off...intense,and ended way too short.
