Biggest thing in killing an opponent fast is being, obviously, faster than he is...  But how can you be faster?  Here are some major things I think create speed and give you an edge over your opponent…  I'll describe how to increase these as well...

1.  Reflexes  -  I believe being physically fit and working out will definitely increase your reaction time and speed…  If you look at any top gamer from the past who competed in a lot of the games I play, most of them are actually in fairly good shape...  A lot of the top gamers came from competitive sports too, so take advantage of this and go run 20-30 minutes everyday…  Takes two seconds to put your shoes on and go do it…  You'll feel a 1,000 times better after you complete it and get back inside to frag some opponents…

I want to talk about teamplay today, because I feel a lot of people go online and don't understand how important it is to roam together or actually have at least one friend to play with.  If your always roaming around by yourself and you die, there is no one to avenge your death.  If you had a teammate there with you, there is a great chance that your teammate will kill that guy, and the score would be then tied 1-1...  After time spent with one friend or one teammate over a period of time, you'll start moving on to more advance tactics, like timing a flashbang while ur friend is going to be uber aggressive close range right after it blows up.  Then its another situation where its 2 against 2 or more opponents who are all flashbanged, and its basically always a win win for your team!

So get your friend or friends together, and try to play as a team...  Communication is huge, so don't be afraid to talk!  Yell and call out spots and eventually make up nick names for each spot in the map if you play it a lot.  This could be your own language after awhile within your team, you'll all be responding and knowing exactly where that guy is camping at.  A lot of times the nick names are to call out someone in a lame or popular spot where enemies usually are during a match.

Hope this helps you out with building some of your basic team skills...

Frag on.

Learning to slide in Quake 4 is a great move to have in your arsenal.  Sliding allows you to get away faster or attack in an unorthodox way.  While jumping around the map you can gain extra distance to your jump by crouching in mid air before you’re about to land.  The better you time your crouch at the end of the jump the further you will slide.  Have fun sliding.
