Er, it's a lot better than two. And xenos only have 4 (or 2, by your logic).
Eh? My logic? What logic? As for having 2 legs, Xenos can go either or, bipedal or quadraped. They actually are more effective movement wise on all fours.

Those "sparks" are the rounds exploding on impact - do any of the aliens hit not explode rather messily? And shotguns aren't exactly great at getting through armour, so they can't be that hard. 
Yes, several. The rest are just pumped so full of bullets at such close range that they might as well have exploded:D As for the shotgun, that was only ever really used at close to medium range, which is more than enough to get it through (some) armor.

Fair enough. But getting smacked very hard with a Glowy Blade Thingy™ would, I think. 
Getting smacked with a Glowy Blade Thingy would hurt just about anyone, I think

A Praetorian would have a chance, I think, because it's bigger, harder and still very fast, so it might get a decent hit on a Shivan before it got toasted/mashed/sat on, but a warrior/drone/runner would get it's ass handed to it, probably as a pile of ash...
IMO, Praetorian, Queen, and the Itty Bitty Facehugger would have a better than average chance, even with the shivans beam cannon or glowy blade
