tinny, it doesn't mean it's illegal... and yeah it's possible but it would be easier to walk through lava then do it.
it's not dead, ensiform.
jk2 is near dead, in comparison between JK3 and JK2, jk2 has about 100 people on v1.04, about 1,000 active total, while on jk3 theres about 5,000 active on both versions. it isn't dead.
if u consider "not dead" games like CSS, CoD4 or CoD2 (xfire.com ranks), i would consider them over-populated games instead of a normal game.
