I'm a bit interested to know what the most popular choices for limb targeting are among xenos, I assume most xenos target legs/feet but recently I saw a marine in DChat complaining about how ravager gang slashed his eyes and made him go blind in two hits which really piqued my curiosity regarding different limbs. Personally I still stick with slashing feet, if nothing else it ensures the marine will get sent back to the Almayer, or in the best case scenario it prevents an isolated target from escaping since without a foot they end up being slower than Gabe Newell after eating 50 McChickens.
I go with groin slashing as well sometimes since it apparently does organ damage, although I haven't been on the receiving end of that as a marine so I'm not sure how damaging it actually is.
I used to slash hands when most weapons required a grip to do anything at all, but in these days a lot of marines carry shotguns which are still deadly even with one hand, so for me hands/arms really aren't as good as they used to be.
Marine input is also appreciated, I'd like to know which limbs marines hate getting slashed the most.
