Initiative Order Problems with Interupted Combat

[czarofprussia]

Hi all,

Quick question about initiative. I was running a game and the PC's had split into two groups and spread out (usually a bad idea.) One group (group A) got into combat with goblins. Eventually the other group (group B) heard the sounds of combat and ran to help. How do you figure initiative when others join in combat?

Thanks.

well the easiest way is to have group 2 arrive to the combat, at the very end of a round, and begin the next round with init in order, if anyone hasn't rolled init, have them do it and proceed the combat with everyone together.

Okay yeah that makes sense. Thanks.
