So hey guys! There is a lot of way to kill yourself easily.

First:
-1. Find a server, and write to the console: kill --> You will die instantly. Thats the fastest suicide in the game but its boring.
-2. Find a big place, and jump off from that place. --> Bigger place = you loose more hp so you will die faster than a smaller place.
-3. This one is pretty easy just make fun of a game where you connected, and just dont fight. People will kill you. --> With friends this one its pretty fun.
-4. Go with solider, demo etc.. caracters with you can kill yourself.
-5. Jump off from the map example: Hightower. --> Instant suicide.

I hope you like my Guide! Its pretty fun, easy and you will not get injured in real life.
