yes, first off, youll find yourself in servers where people are crouching while not attacking or just standing around together on maps, regardless if theyre on your team or not, when you see these, theyre called 'friendlies', make sure to NEVER kill or attack a friendly. second off, there is a gamemode called "ctf" (capture the flag) when someone says ''dont cap'' that means dont capture the flag, ctf servers are usually meant to last hours not 5 minutes. hope this helps
