Ya, I'm digging it. When you shoot someone... they die. Not having to pump 50 rounds into a guy with the M60 to take him down is fun.
No 'spotting' means you have to hunt your opponents and use voice chat to find targets.
Some red-sights work, others don't.
No ammo counter... you have to mind your loads.
Friendly-Fire? Well, so far I found that the folks playing hardcore are a bit wiser about their spray.
Word is... some of the hardcore servers are sniper farms because of the one-shot kill issue. Oh well.
I know that not everyone likes it but I'd like to run our server this way every now and then.
