Correct answer is to not be alone. Having a teammate increases your chance of survival by WAY more than 75% for sure. Shake cancels stun and this is the only thing lurker has.
But let’s imagine the question is “how to solo lurkers”.
First of all, to win 1v1 against a lurker you need to avoid its main skill (that basically is made to win 1v1), you need to dodge the pounce. The easiest way to dodge the pounce is to be fast. So light armor or even better no armor is what you need. There are fraggers that are extremely good at movement prediction who can dodge even in heavy armor though.
Pounce has a 5 seconds CD and lurker will run out of invisibility eventually. Plus the more lurker misses, the more irritated it gets, and tends to miss more. So keep dodging and shooting.
The best guns are the ones that don’t have wield slowdown, so it’s m39 and m4ra. You can outrun a lurker off weeds with these weapons. Shotgun is very good if you hit PB on the lurker (LRB also works as it still applies slowdown), and a missed pounce is the best opportunity (you still need sidearm to finish the lurker off though). It’s possible to PB/LRB the lurker mid-pounce. Flamer can work, it also helps to control the battlefield. If you lit the lurker on fire, he most likely will try to run away, if you also land a few shots on the lurker, he will likely die. GL/UGL is another interesting choice that can work, as nade stun also applies huge slow. Airburst nades can basically one shot because they are broken.
If you fight an invisible lurker, switch your MD to short range. Shoot at pings. Spray and pray actually. Lurker doesn’t have much health and CANNOT really afford to tank damage. So just shooting in the darkness may force the lurker to disengage, unless he gets cocky (but then it’s way easier to kill the lurker if he’s wounded).
If you got pounced it’s usually over. Unless it is not. If you are premeded (ideally on as much meds you can put in your blood, so tric, myraline, etc) you can actually survive several pounces if lurker cannot immediately follow up with slashes after you get up: shoot the lurker to make him wait for invis CD for pounce, invis CD is quite long so you can regen a lot of HP in the meantime. Keep trying to dodge the pounce, move unpredictably. You will be slow (from pounce slowdown and fracs), but pounce is never guaranteed to hit. Armor also helps with this strategy, as it’s easier to avoid paincrit.
So bottomline, be premeded, shoot non-stop, move unpredictably.
