Raging does not help ------> What you should do instead...
I just want to say that raging does not help or do you any good. If your team is failing or losing, why rage? Might as well throw your PC out the window or smash it...
Anyway, I know it is frustrating to lose and fail all the time. We all want to win and succeed. However, to some people, losing one time already means "the end of the world". Really? That's nonsense! It's a game. Don't let those losses go to your head. If you lose or fail, you can learn from it. Think: What did you or your team do wrong? If your strategy isn't working, what other strategies can you or your team form to succeed?
If you have 1 bad teammate* on your team, you have a few options: 1. Leave the game (Not recommended) 2. Vote to kick (May seem harsh, but if you have no choice, you have to do it) 3. Tell them to stop what they are doing (If they don't listen, go for Option 2)
*A player who: - Leaves the team behind - Has the "I can solo this" attitude - Hogs all the healing items - Runs in front of your line of fire - Purposely kills teammates - Ignores instructions
Make sure your team communicates often. Use your microphone or the chat to communicate. Chet Faliszek, the game's writer, said that communication is important in L4D2.
To all new players, please, DO NOT jump straight into versus, realism, survival and scavenge modes. It is highly recommended that you play campaign/single player first (preferably Single Player) to learn the game basics. Once you are familiar with the campaigns, weapons, and gameplay, go ahead and play online Campaign mode. If you do want to play Versus mode, go ahead, but expect yourselfs to be kicked often...there's no room for mistakes in public Versus games (although there are cases where a team of inexperienced players kick the best player on the team...)
Lastly, if your team is not doing well, don't get angry. Re-formulate your strategy. Work with your teammates. "Strategy is as important as speed. Be patient and aim for the win" (from Gran Turismo 4)
