Should you join my server you'll see 'Chaos Duel' and 'Chaos Duel - Extras'. The first variation is what I and my former Generals Clan mates call 'Traditional', ie no gravbelt, 'kick', grapple, etc. These are the Chaos features that you normally see in the other Chaos gametypes as they (technically the ChaosUT2 mutator) are auto-loaded. Obviously then, the second variation ('... Extras') contains all of these features, which tends to make the duels more fun to most of us. gen.k4b.00d.135.BLZ seems to enjoy using the gravbelt as an aid in his slaughtering of us in Duel

Anyway if you haven't spotted it already, server IP is in my sig.
