Here are mods for dismemberment:
Dismemberment mod
JK3 Multiplayer Dismemberment
As for the SP JKA has a very short SP and can get boring.The MP is okay but JKO's SP plot is better.That's why i play the mod i told you about.JKO MP has the same ammount of players as the players in JKA 1.00...mabye a bit more.I haven't played 1.01 so i don't know if the servers are full or not.
