Cmon Thunder.......
Not to flame anyone here, but i am an avid UT player, and jumping is not the key at all. I think jumping helps a bunch, but only in particular occasions.
Some Tricks of the Trade
1. Get to know your guns, the better you are with them, the more kills you get.
2. Some tactics are nice too, i like a little bit of a all out assault, find your best tactic and use it.
3. Find what kind of player you are...Do you snipe (by god thats me, (i got 62 snipes in a game the other day...don't believe me...ask jonnyboy) If you are an assaulter, then get good at that.
4. Learn your limits...if you know you can't do something, don't...you will end up looking like and ass.
5. Taunt, mostly pelvic thrust, but do anything to prevent yourselve from having any allies...its more fun this way...
feel free to give me some advice too..i always am looking for new ways to improve my game.
