After much experience with the Laser-Guided-missile skills from Half-Life, I'd say I've gotten good enough to give shrieker tips. ^_^ -Much like the Hive Cannon, You can only kill somebody so fast. So you can't take on a good SCAR and USP player. -I find it comes in handy for those players who always jump for cover whenever they get so much as a scratch. If you can figure out how to understand depth perception where you don't actually have it, you'll surely be able to go right around that flimsy cover. -It will really help you out to put a focus on it.
its ok. Its not as powerful when you use the straight faster shots. just matters what you like --- Conduit2 FC: 2923-9534-5683 http://www.youtube.com/watch?v=f1gj_Yn6t7A&feature=BFa&list=PLC305A56B8534F393
Use both Energy Focusses. Then go for 3 body shots, this should be enough to kill an unamored person.
Don't shoot at their legs though and don't go for splash damage, this way it might require 6 shots and that's total ammo waste.
And if you're fighting against high rate fire weapons, such as the SCAR and USP, use the Alternate Fire mode or the Normal mode in close combat (I prefer Normal Mode). If it's a distance combat, you could try the Normal mode, but I would suggest that you better run and try to close the distance gap because in this situation the Shrieker will probably lose due to a lower fire rate.
