Ahh, so NOW you people download it... not when I post about it...
Tips? Play with random bots for a while, so you get used to all of them, then you can pick a favourite or just keep playing random... Use the powerups that you can get before you start a game (they're free! took me a while to realize that). Never go in a game without a double shot and a teleport... Learn how to use delay to your advantage - it's probably the most important thing to learn. Delay determines the order you go in, if you play it right you can get 2, sometimes even 3 shots before your opponent goes again (standard trick: your opponent, who's already fairly injured, just used a double shot on you, so their delay is pretty high; use a normal shot on them, then you should get another turn, use a double shot and you might get the kill). Use Weapon 1 as a "tracer" to set up your shot because of its lower delay, then use Wep2 for the real damage - unless you're absolutely sure you're gonna hit. And, of course, know the bots... for many weapon 2 is not always the best. There's several ways to shoot - slice is the standard one, you hold & release the space bar. Drag uses the mouse, I found it a bit harder at first but I use it exclusively now. Sniper I still haven't figured out - I think it's the same as drag except you can set a marker to remind you how hard to shoot. Try all three, and see which one you prefer...
I could go on for several pages, let me know if you want me to. LOL
